How To Write A Range Of Numbers In If Condition Js

Creates a function that invokes func with the arguments of the created function. If func is a property name, the created function returns the property value for a given element. If func is an array or object, the created function returns true for elements that contain the equivalent source properties, otherwise it returns false. Fetch the default set of models for this collection from the server, setting them on the collection when they arrive. The options hash takes success and error callbacks which will both be passed as arguments. When the model data returns from the server, it uses setto merge the fetched models, unless you pass , in which case the collection will be reset.

Delegates to Backbone.syncunder the covers for custom persistence strategies and returns a jqXHR. The server handler for fetch requests should return a JSON array of models. When returning a JSON response, send down the attributes of the model that have been changed by the server, and need to be updated on the client. When responding to a "read" request from a collection (Collection#fetch), send down an array of model attribute objects. The exact meaning of this header field depends on the implementation of the origin server and the nature of the original resource. For files, it may be just the file system last-modified time.

For entities with dynamically included parts, it may be the most recent of the set of last-modify times for its component parts. For database gateways, it may be the last-update time stamp of the record. For virtual objects, it may be the last time the internal state changed. Parse is called by Backbone whenever a collection's models are returned by the server, in fetch.

The function is passed the raw response object, and should return the array of model attributes to be addedto the collection. The default implementation is a no-op, simply passing through the JSON response. Override this if you need to work with a preexisting API, or better namespace your responses. By default save checks validate before setting any attributes but you may also tell set to validate the new attributes by passing as an option. If called with no arguments, first emits the first value of the source Observable, then completes.

If called with a predicate function, firstemits the first value of the source that matches the specified condition. It may also take a resultSelector function to produce the output value from the input value, and a defaultValue to emit in case the source completes before it is able to emit a valid value. Throws an error if defaultValuewas not provided and a matching element is not found.

Expand will re-emit on the output Observable every source value. Then, each output value is given to theproject function which returns an inner Observable to be merged on the output Observable. Those output values resulting from the projection are also given to the project function to produce new output values.

Count transforms an Observable that emits values into an Observable that emits a single value that represents the number of values emitted by the source Observable. If the source Observable terminates with an error, countwill pass this error notification along without emitting a value first. If the source Observable does not terminate at all, count will neither emit a value nor terminate. This operator takes an optional predicate function as argument, in which case the output emission will represent the number of source values that matched true with the predicate. WhenfromEvent is used with event target of that type, you can provide this values as third parameter as well.

Optionally forkJoin accepts project function, that will be called with values which normally would land in emitted array. Whatever is returned by project function, will appear in output Observable instead. This means that default project can be thought of as a function that takes all its arguments and puts them into an array. Note that project function will be called only when output Observable is supposed to emit a result. Most of the loops you'll write in CoffeeScript will be comprehensions over arrays, objects, and ranges. Comprehensions replace for loops, with optional guard clauses and the value of the current array index.

Unlike for loops, array comprehensions are expressions, and can be returned and assigned. The Expires entity-header field gives the date/time after which the response is considered stale. A stale cache entry may not normally be returned by a cache unless it is first validated with the origin server .

See section 13.2 for further discussion of the expiration model. Returns an Observable that emits items based on applying a function that you supply to each item emitted by the source Observable, where that function returns an (so-called "inner") Observable. Each time it observes one of these inner Observables, the output Observable begins emitting the items emitted by that inner Observable. When a new inner Observable is emitted, switchMapstops emitting items from the earlier-emitted inner Observable and begins emitting items from the new one. It continues to behave like this for subsequent inner Observables. Note that project does not take as argument that array of values, but values themselves.

That means default project can be imagined as function that takes all its arguments and puts them into an array. Added an _.defaults function, for use merging together JS objects representing default options. Added an _.once function, for manufacturing functions that should only ever execute a single time.

_.bind now delegates to the native ES5 version, where available. _.keys now throws an error when used on non-Object values, as in ES5. For strings and array-like objects _.isEmpty checks if the length property is 0. For other objects, it returns true if the object has no enumerable own-properties.

Note that primitive numbers, booleans and symbols are always empty by this definition. Memoizes a given function by caching the computed result. If passed an optional hashFunction, it will be used to compute the hash key for storing the result, based on the arguments to the original function. The default hashFunction just uses the first argument to the memoized function as the key.

The cache of memoized values is available as the cacheproperty on the returned function. You can use either numeric or string expressions as arguments for comparison functions. (String constants must be enclosed in single or double quotes.) The expressions can be literals or values fetched by a query. Comparison functions are most often used as filtering conditions in WHERE clauses, but they can be used in other clauses.

It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard. If multiple encodings have been applied to an entity, the content codings MUST be listed in the order in which they were applied. Additional information about the encoding parameters MAY be provided by other entity-header fields not defined by this specification. Perhaps the single most common JavaScript "gotcha" is the fact that when you pass a function as a callback, its value for this is lost. View events are automatically bound to the view's context for you.

You may also find it helpful to use _.bind and _.bindAllfrom Underscore.js. Convenience to create a new instance of a model within a collection. Equivalent to instantiating a model with a hash of attributes, saving the model to the server, and adding the model to the set after being successfully created. If client-side validation failed, the model will be unsaved, with validation errors.

In order for this to work, you should set the model property of the collection. The create method can accept either an attributes hash and options to be passed down during model instantiation or an existing, unsaved model object. Adding and removing models one at a time is all well and good, but sometimes you have so many models to change that you'd rather just update the collection in bulk. Use reset to replace a collection with a new list of models , triggering a single "reset" event on completion, and without triggering any add or remove events on any models. For convenience, within a "reset" event, the list of any previous models is available as options.previousModels. Add a model to the collection, firing an "add"event for each model, and an "update" event afterwards.

If a model property is defined, you may also pass raw attributes objects and options, and have them be vivified as instances of the model using the provided options. Pass to splice the model into the collection at the specified index. Parse is called whenever a model's data is returned by the server, in fetch, and save. The function is passed the raw response object, and should return the attributes hash to be set on the model. The normalization rules are written in a specific syntax, allowing you to create rules to affect specific changes to records.

For example, you can edit or delete fields, and you can also do that conditionally, based on some other condition that takes place or doesn't in the bibliographic record. The return or result "parameters" of a Go function can be given names and used as regular variables, just like the incoming parameters. When it projects a source value to an Observable, the output Observable begins emitting the items emitted by that projected Observable. However, exhaustMap ignores every new projected Observable if the previous projected Observable has not yet completed. Once that one completes, it will accept and flatten the next projected Observable and repeat this process. CombineLatest combines the values from this Observable with values from Observables passed as arguments.

Note that if event target calls registered function with more than one argument, second and following arguments will not appear in resulting stream. In order to get access to them, you can pass to fromEvent optional project function, which will be called with all arguments passed to event handler. Output Observable will then emit value returned by project function, instead of the usual value. Optionally, a selector function can be passed to bindObservable. The selector function takes the same arguments as the callback and returns the value that will be emitted by the Observable.

Even though by default multiple arguments passed to callback appear in the stream as an array the selector function will be called with arguments directly, just as the callback would. This means you can imagine the default selector as a function that aggregates all its arguments into an array, or simply returns first argument if there is only one. The output of bindCallback is a function that takes the same parameters as func, except the last one . When the output function is called with arguments it will return an Observable.

If function funccalls its callback with one argument the Observable will emit that value. If on the other hand the callback is called with multiple values the resulting Observable will emit an array with said values as arguments. Assigns own and inherited enumerable string keyed properties of source objects to the destination object for all destination properties that resolve to undefined. Once a property is set, additional values of the same property are ignored. _.bindAll now takes the context object as its first parameter.

If no method names are passed, all of the context object's methods are bound to it, enabling chaining and easier binding. _.functions now takes a single argument and returns the names of its Function properties. Added _.isRegExp so that isEqual can now test for RegExp equality. All of the "is" functions have been shrunk down into a single definition. Each window function requires an OVER clause that specifies the window top and bottom. The three components of the OVERclause provide additional control over the window.

Partitioning enables you to divide the input data into logical groups that have a common characteristic. Ordering enables you to order the results within a partition. Framing enables you to create a sliding window frame within a partition that moves relative to the current row. You can configure the size of the moving window frame based on a number of rows or a range of values, such as a time interval.

The WHERE clause, sometimes called the predicate, filters records produced by the FROM clause using a boolean expression. Multiple conditions can be joined by boolean AND and OR clauses, optionally surrounded by parentheses—()— to group them. CoffeeScript loops no longer try to preserve block scope when functions are being generated within the loop body.

Instead, you can use the do keyword to create a convenient closure wrapper. Added a --nodejs flag for passing through options directly to the node executable. Better behavior around the use of pure statements within expressions. Fixed inclusive slicing through -1, for all browsers, and splicing with arbitrary expressions as endpoints. A cache MAY assume that the same selection will be made for future requests with the same values for the listed field names, for the duration of time for which the response is fresh.

If multiple encodings have been applied to an entity, the transfer- codings MUST be listed in the order in which they were applied. When the no-cache directive is present in a request message, an application SHOULD forward the request toward the origin server even if it has a cached copy of what is being requested. This pragma directive has the same semantics as the no-cache cache-directive (see section 14.9) and is defined here for backward compatibility with HTTP/1.0.

Clients SHOULD include both header fields when a no-cache request is sent to a server not known to be HTTP/1.1 compliant. That is, if no entity tags match, then the server MUST NOT return a 304 response. When a directive appears without any 1#field-name parameter, the directive applies to the entire request or response. When such a directive appears with a 1#field-name parameter, it applies only to the named field or fields, and not to the rest of the request or response. This mechanism supports extensibility; implementations of future versions of the HTTP protocol might apply these directives to header fields not defined in HTTP/1.1. Each model can be a Model instance, an id string or a JS object, any value acceptable as the id argument of collection.get.

Fires a "remove" event for each model, and a single "update" event afterwards, unless is passed. The model's index before removal is available to listeners as options.index. Override this property to specify the model class that the collection contains. If defined, you can pass raw attributes objects and options to add, create, and reset, and the attributes will be converted into a model of the proper type using the provided options, if any. Merges the model's state with attributes fetched from the server by delegating to Backbone.sync. Useful if the model has never been populated with data, or if you'd like to ensure that you have the latest server state.

Triggers a "change" event if the server's state differs from the current attributes. Fetch accepts success and error callbacks in the options hash, which are both passed as arguments. A Model manages an internal table of data attributes, and triggers "change" events when any of its data is modified. Models handle syncing data with a persistence layer — usually a REST API with a backing database. Design your models as the atomic reusable objects containing all of the helpful functions for manipulating their particular bit of data.

How To Get Windows 10 License Key From Command Prompt

If your new computer comes with preinstalled Windows 10 software, the product key is stored in the motherboard firmware / BIOS. Launch command prompt by searching CMD from the Windows search bar.

Generally, if you bought a desktop or laptop from OEMs like Dell, HP, etc, you will find it on a sticker on the machine itself. However, that may not be the case for other machines. In those cases, you need a different way to find Windows 10 serial key. The problem is, Windows 10 doesn't display the serial key directly for security reasons.

Rather, it shows the product key which is completely different from the license key. One click and that wizard retrieved our digital license, despite not being linked to a Microsoft account. And again, this was for a retail key that was originally used on a desktop which was cloned as a Windows To Go drive and plugged into another machine with a different hardware profile. In other words, with luck, Microsoft's activation is forgiving enough and you should have no issues validating your OS license on a new machine or after several hardware changes. Looking for way to find your Windows 10 product key? Need Windows 10 product key in order to reinstall or move it to a new computer?

Here this post we go through steps to find windows 10 product key using command prompt. Also, discuss how to find windows 10 product key after upgrade. To display the expiration date of the current license, run the following command.

This is only useful for Windows system activated from an organization's KMS server, as retail licenses and multiple activation keys result in a perpetual license that won't expire. If you haven't provided a product key at all, it'll give you an error message. The methods listed in this article will help you to check whether the Windows 10 product key you have bought or currently using is genuine or not.

It is just a one-time investment as you will get the lifetime license. Most third-party vendors are untrustworthy and lure users by offering fake offers. With the launch of Windows 10, product keys have become less important because Microsoft launched digital licenses in 2016. Digital licenses allow for the simple installation of an operating system without requiring a bootable device. The operating system can be activated via your Microsoft account. Even when you're reinstalling Windows 10, the system detects the license automatically.

How To Get Windows 10 Serial Number From Command Prompt Since Windows 10, Microsoft has changed the way Windows license works. Irrespective of how you got your license, once activated, the product key is tied to your system hardware. Whether you upgrade to the next version or clean install the OS, the licensing code component will automatically detect and verify the ownership.

In earlier days, Windows PC manufacturer was used to paste a sticker on a computer or laptop to see a 25-digit product key or license key. It is a 25 digit code that is used to activate your Windows installation. When you install a fresh copy of Windows after formatting, the same key is used to activate your PC from the Microsoft server.

It helped me activate windows 10 on my ASUS 11th Gen i7 Lapotop. For some reason, it said windows was not activated and I did not know how to retrieve the keys since its also embedded on the motherboard? The command prompt instruction worked for me like a charm. A product key is usually required when uninstalling or reinstalling Windows 10.

If you're able to boot into your Windows 10 system then it will be easy to retrieve your product key without complex command prompt. Windows registry stores all system information in itself and control your system with hot key. You can navigate to your license directly from the Windows registry.

Sometimes when you need to a reinstall your windows 10 on your PC, then you must to find out Windows 10 activation key before re-installing system . Below we have mentioned two steps to find the Windows 10 product key. Nowadays, if you purchase a preinstalled Windows 10 PC, you might be wondering how to find your key.

You would be unable to find the sticker on the machine, and the computer manufacturer doesn't include one in the box. Windows PC manufacturer has started embedding product keys in the BIOS, and hence there is no need for a sticker to affix on the computer or laptop. This makes it easy if you ever want to reinstall or upgrade Windows. Windows OS will find the key from BIOS, and there is no need to type the key even when you install a fresh copy of Windows.

Whether you installed and activated Windows yourself, or it came preinstalled, your product key is stored in the BIOS. This makes it really easy if you ever want to reinstall or upgrade Windows – there's no sticker on the machine that could get damaged, and no small label to lose. However, if you are building a custom PC, you will have to buy the retail product key for Windows.

Keep in mind that you can keep using this retail key as you upgrade your hardware over time. On the other hand, the product key that comes with Windows laptops is tied to its motherboard and can only be used on that particular laptop. So that's a brief explainer on what is a product key for Windows. Now that you have your product key, download Windows 10 ISO file and burn it onto the USB drive.

You can clean install Windows 10 again on the same PC using the same product key. Windows will automatically activate your license after the installation of Windows 10 on the same hardware. There are many reasons to change your Windows 10 product key. It may be you want to change product key to upgrade your edition of Windows 10. The current product key may be invalid , and you want to replace the current product key with a new key without having to reinstall Windows 10. Windows 10 provides five simple methods to change the Windows 10 product key.

If you plan to reinstall your operating system or simply want to deactivate the windows 10 product key on your system you can by following these steps. There are many different ways that windows 10 product keys are stored such as, on a sticker, embeded in to the computers motherboard, digitally, online, KMS and a few more. Below I will go through the steps you will need to take to find your windows 10 product key.

If you want a simple way to find the product key, you can use a utility like Produkey viewer by Nirsoft to retrieve the key for you fast and easy. On installation, Produkey retrieves the Windows license key among other keys you may have lost i.e. office. A Windows license key or product key is a 25 character code used for activating Windows. If you have the latest Windows 10 the code comes in digital form or as a box if bought from a physical store. If you have bought Windows earlier and you lost the box or the Tag behind your laptop or the email with digital delivery and are now facing problems in upgrading Windows.

This tutorial may help you to recover your Windows License key from the computer. It is when you make major hardware changes, such as replacing the motherboard, you will require to reactivate the Windows with the product key. Follow the steps in the article and you should be able to retrieve your product key in no time. However, if you still cannot recover the key, try contacting Microsoft support for further assistance. In fact, it is totally free to activate windows 10 using this method and you do not require any product key or activation key.

For digital license – You don't need to supply the product key to activate Windows 10 or Windows 11 on same PC, just link your Microsoft account to Windows 10 before upgrade. Before we begin, note that the success of any of these methods is largely dependent on how your PC was activated. However, if your PC was activated as part of an organization's licensing agreement, finding a product key may be more problematic. Use this slmgr command to remove the product key from Windows Registry. Doing this will not delete the key from your computer or un-activate Windows, but it will prevent key finder programs and malicious tools from being able to retrieve the key.

When you buy a copy of Windows 10, you should get a activation key which can be used to activate your Windows. You must keep it noted somewhere in case you will be required to activate again. Earlier Windows Product key was always placed outside the machine in a sticker and we used to try our best to protect it. But now, thanks to Microsoft, that now they have started storing the license key within the machine's UEFI/BIOS. The information can now be easily obtained by running a few commands on your computer and now you do not have to worry about losing it. So these are the five ways you can use to find the Windows 11 product key on your PC.

For me, running the command on the CMD window worked like a charm. If that didn't work for you, the third-party tool is an excellent alternative. Not to mention, you still have the VBS script that displays your license key instantly.

If you want to learn the difference between Windows 11 Home and Pro, go through our in-depth comparison. And to legally buy a Windows license key at a lower cost, head over to our linked article. And if you have any questions, let us know in the comment section below.

If you have a Windows laptop, the license sticker is generally glued to the underside of the computer. Just turn back your laptop and look for a 25-character product key. Keep in mind, if you bought the laptop running Windows 10 or 7, the license key will still work without any issues on your upgraded Windows 11 PC. In summary, it has come out clear that it is possible to retrieve Windows 10 product key.

All the methods explained above are fully dependable. If all these above methods cannot find the product key, you might as well try the free Product key finders, that may be helpful to you. You might fail to understand how essential and vital Windows 10 product key is until you are being faced by the need to upgrade or clean install the system. We hope you are informed Microsoft rolled out a new strategy for its products and stopped providing free system upgrade back in 2016.

Back to Windows 10 product key, the majority of users are not aware of where it is placed. This gets to be even more complicated and confusing because Microsoft stationed the key right in the registry and to be read by software, if not by humans. The good think about the product key is it can be recovered even for that computer which doesn't boot anymore, only if you can get reach to the disk drive from a working computer.

To display very basic license and activation information about the current system, run the following command. This command tells you the edition of Windows, part of the product key so you can identify it, and whether the system is activated. It is by far the fasted method to activate the windows 10 product.
