Use **ES6** for the `gulpfile.js` To Do: - [x] Create .babelrc with the es2015 preset. - [x] Install the next dependencies: `npm i --save-dev babel-core` `npm i --save-dev babel-preset-es2015` - [x] Rename `gulpfile.js` => `gulpfile.babel.js` - [x] Move the code to ES6. - [x] Update linter rules to enable es2015 syntax.
