5/26/2023 0 Comments What is es6 javascriptIt can be used from the command line with a simple command, and can also easily be added to your webpack configuration. Babel is a tool that takes your modern JavaScript code and transpiles it to code that older browsers can understand. But in the real world, if you’re selling products to customers you can’t control which browsers people will use to connect to your site.įortunately there is a solution to this problem. This means, unfortunately, that if you write code that uses these new features it will not run in browsers that do not support it.įor most of us, this has not been an issue because you are almost definitely using a new browser that automatically updates itself when a new version is released. At the current time all modern browsers (Chrome, Firefox, Safari and Edge) support all of ES6, and most of ES7, but older browsers (various versions of Internet Explorer for instance) do not. The problem with JavaScript constantly updating and adding features is that it sometimes takes web-browsers a while to catch up and implement new features once they’ve been released. As we’ve mentioned you’ve already been using many of these, though there are a few we haven’t specifically covered yet. This document outlines all the new features that showed up in ES6.This article provides a nice clean explanation and timeline of the various ECMAScript releases.Part of the confusion here is that right after the release of ES6, the committee that makes these decisions changed the naming scheme from ‘version numbers’ (ES5, ES6, ES7 etc.) to ‘release years’ (ES2015, ES2016, ES2017 etc.) You have probably also come across articles talking about features in ES7 or ES8 or ES2015 or ES2017 etc. If you have been following our lessons you have already been learning these new features because, well, ES6 is just JavaScript. It included many new features that make writing JavaScript much easier and cleaner. Put simply, ES6 is a version of JavaScript that was officially released in the summer of 2015. We’ve been throwing around the term ES6 since our very first lessons, but we haven’t taken the time to properly explain what it means or to investigate the implications of it in our code.
