Different versions of JavaScript

JavaScript is not a static language. It evolves over time to add new features, fix bugs, and improve performance. The official name of the JavaScript language is ECMAScript, which is defined by a standard specification maintained by an organization called ECMA International. The specification defines the syntax, semantics, and features of the language.

The ECMAScript standard and its editions

The ECMAScript standard has several editions, each corresponding to a year or a version number. The first edition was released in 1997, and the latest edition is ECMAScript 2020 (or ES11). Each edition adds new features or changes to the language, such as:

Edition

Year

Features

ECMAScript 2015 (ES6)

2015

Let and const keywords, arrow functions, classes, modules, promises, template literals, destructuring, default parameters, rest and spread operators, etc.

ECMAScript 2016 (ES7)

2016

Exponentiation operator (), Array.prototype.includes method, etc.

ECMAScript 2017 (ES8)

2017

Async and await keywords, Object.values and Object.entries methods, String.prototype.padStart and String.prototype.padEnd methods, trailing commas in function parameters, etc.

ECMAScript 2018 (ES9)

2018

Spread and rest properties for objects, async iteration, Promise.prototype.finally method, RegExp lookbehind assertions, RegExp named capture groups, RegExp dotAll flag, etc.

ECMAScript 2019 (ES10)

2019

Array.prototype.flat and Array.prototype.flatMap methods, Object.fromEntries method, String.prototype.trimStart and String.prototype.trimEnd methods, optional catch binding, Symbol.prototype.description property, etc.

ECMAScript 2020 (ES11)

2020

BigInt primitive type, Nullish coalescing operator (??), Optional chaining operator (?.), String.prototype.matchAll method, Dynamic import syntax, globalThis object, etc.

The browser support and compatibility issues

Not all web browsers support the same version of JavaScript. Some browsers may not support the latest features or syntax of the language. This can cause compatibility issues when you run your JavaScript code on different browsers or devices. To check the browser support for a specific JavaScript feature, you can use websites like:

Website

A website that provides documentation and learning resources for web developers, including JavaScript reference and tutorials. It also shows the browser compatibility table for each JavaScript feature.

Babel

A tool that helps you transpile your JavaScript code from a newer version to an older version that is supported by more browsers. It also lets you use experimental features that are not yet part of the standard.

How to run JavaScript code

Once you have downloaded or written your JavaScript code, you may want to run it and see the result. There are different ways to execute JavaScript code, depending on where and how you want to run it. Here are some of the most common ones:

Using the script tag in HTML

The simplest way to run JavaScript code on a web page is to use the script tag in HTML. The script tag allows you to embed JavaScript code directly in your HTML document, or link to an external JavaScript file or URL. For example, you can write:

&lt;script&gt; // Your JavaScript code goes here &lt;/script&gt;

Or:

&lt;script src="your-file.js"&gt;&lt;/script&gt;

Or:

&lt;script src="

The script tag can be placed anywhere in your HTML document, but it is usually recommended to put it at the end of the body tag, so that it does not block the rendering of the rest of the page. You can also use the async or defer attributes to control when and how the script is executed.

Using an external file or URL

If you have a lot of JavaScript code, or if you want to reuse it across multiple web pages, you may want to save it as an external file or URL. This way, you can keep your HTML and JavaScript code separate, and make your code more modular and maintainable. To use an external file or URL, you need to link to it using the script tag, as shown above. You can use any file extension for your JavaScript file, but .js is the most common one. You can also use any URL that points to a valid JavaScript file, such as a CDN (Content Delivery Network) or a GitHub repository.

Using the console or debugger tools

If you want to test or debug your JavaScript code, you can use the console or debugger tools that are available in most web browsers. The console is a panel that lets you enter and execute JavaScript commands, and see the output or errors. The debugger is a tool that lets you set breakpoints, step through your code, inspect variables, and more. To access the console or debugger tools, you can use the keyboard shortcut Ctrl+Shift+I (Windows) or Cmd+Option+I (Mac), or right-click on the web page and select Inspect or Inspect Element.

Using Node.js or other runtime environments

If you want to run JavaScript code outside of a web browser, such as on a server or a device, you need to use a runtime environment that can execute JavaScript code. A runtime environment is a software platform that provides the necessary features and resources for running a specific type of code. One of the most popular and widely used runtime environments for JavaScript is Node.js. Node.js is a free, open-source, and cross-platform platform that allows you to run JavaScript code on the server-side, as well as develop applications, tools, and libraries. To use Node.js, you need to download and install it from its official website: . There are also other runtime environments for JavaScript, such as Deno, Rhino, or GraalVM, that you can explore and use.
