ECMAScript 6 (ES6, specification at http://www.ecma-international.org/ecma-262/6.0/) has many nice features, but presently not all browsers support ES6. However you can still develop your applications in ES6 and make it run in all browsers. For this you need what is called as transpiler – which converts ES6 code to ES5, which all browsers understand currently.
One of the popular transpiler is Babel . In this post we will see how to use Node.js (https://nodejs.org/), Gulp.js (https://gulpjs.com/), Browserify (http://browserify.org/) to compile ES6 code to ES5.
Gulp is a build tool for Node.js applications. Browserify resovles ‘require’ modules of Node.js and bundles all modules in one file. We will first use browserify to combine all our JS code in one file and then feed the output to babelify to translate the code to ES5. Structure of this sample project is as follows –

Not all the files are folders are shown above, for example package.json and node_modules folder are not shown.
