This means converting ES6 JavaScript into ES5 JavaScript. We have to transpile our code so that a wider range of browsers understand our JavaScript.In order to reap the benefits of ES6 today, we have to do a few things to get it to work in as many browsers as we can: For instance, Internet Explorer 11 does not support ES6, but has about 12% of the browser market share. But it will be some time until older versions of web browsers are phased out of use.

ES6 is almost fully supported by all major browsers.

Therefore, if you've written or seen any JavaScript in the recent past, chances are it was ES5.ĮS6 is a new version of JavaScript that adds some nice syntactical and functional additions. It has been supported by all major browsers for several years. These opaque acronyms can get confusing quickly.ĮS5 (the ES stands for ECMAScript) is basically 'regular JavaScript.' The 5th update to JavaScript, ES5 was finalized in 2009. In any cursory search on the Internet looking for React material, no doubt you have already run into the terms JSX, ES5, and ES6. In this article, we're going to look at one part of the React ecosystem: ES6 and JSX. In our previous article, we looked at what React is and discussed at a high-level how it works. Now that we know what React is, let's take a look at a few terms and concepts that will come up throughout the rest of the series.
