(ES6) code snippets extension adds snippets for ES6 (ECMAScript 6) syntax. ECMAScript (file format) Filename extensions. It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications.ĮCMAScript 2021, the 12th edition, introduces the replaceAll method for Strings Promise.any, a Promise combinator that short-circuits when an input value is fulfilled AggregateError, a new Error type to represent multiple errors at once logical assignment operators ( ?=, &=, ||=) WeakRef, for referring to a target object without preserving it from garbage collection, and FinalizationRegistry, to manage registration and unregistration of cleanup operations performed when target objects are garbage collected separators for numeric literals ( 1_000) and was made stable.

Since publication of the first edition in 1997, ECMAScript has grown to be one of the world's most widely used general-purpose programming languages.

It is the twelfth edition of the ECMAScript Language Specification. 3 Only has partial Symbol support and partial support for RegExp.prototype properties. 2 Does not support tail call optimization. 1 Notable partial support in IE11 includes (at least some) support for const, let, block-level function declaration, typed arrays, Map, Set and WeakMap.

In this tutorial we are going to learn about the new features we can use in the latest version of ECMAScript 2021 with some coding examples One of the possible solutions to recreate this function is: Number. The implementation of this method was pretty easy, but it’s still good to have it natively. This method returns true if the passed value is an integer, and false otherwise.

It determines whether the value passed to the function is an integer or not. It’s a new addition to JavaScript, and this is something you may have defined and used by yourself in the past. The first method I want to cover is Number.isInteger().
