Since ES 2015, transpiling JavaScript has become very common. Transpilation is a source-to-source compilation in which newer versions of JavaScript are used, and a transpiler rewrites the source code so that it is supported by older browsers. Usually, transpilers transpile down to ES3 to maintain compatibility with all versions of browsers. From version 2, the compiler produces code compatible with the latest versions of ECMAScript. For example, every time you use a class , you get a class in JavaScript. The below that is listed code makes use of the JavaScript to create and define the HTML5 elements for IE versions such as IE6, IE7 and IE8. Once the code is enclosed in a conditional statement, you will see the other compatible browsers simply ignoring the code and move on through the remaining mark-up.
