The easiest way to do that is to use the Babel compiler, which can translate all of the new ES6 syntax and features into equivalent ES5 code that older JavaScript interpreters can understand. But remember, older browsers with older JavaScript interpreters won't be able to recognize these new syntax features unless you compile them to their ES5 equivalents. This tutorial will familiarize your with the key ES6 features that React utilizes heavily so that you're better prepared to learn the React framework.Įven if you don't use React, these new ES6 features might be useful to you. ![]() ![]() One framework in particular has eagerly embraced these new syntax features: React. ![]() This version introduced several new features that were sorely missing from the language, but it also included entirely new syntax that makes particular styles of programming easier. In 2015 they released a new version of that specification, officially known as "ECMAScript 2015," but many developers refer to it by the working name "ES6," as it was considered the sixth version of the language.
