Deprecate jQuery to vanilla JS to write es6 and beyond using babel

[markoboy]

Hello, it would be nice if we could write in vanilla JS and use a task runner like Gulp to merge and minify JS files using babel. In addition to that we could separate the code into modules and use gulp-useref to merge all the files together. I believe that the bellow tasks are required in order to move away from jQuery and start using a task runner with a modular approach.

• Rewrite jQuery code to vanilla JavaScript
• Add Gulp (or any other task runner)
• Use babel to transpile code for global browser support
