ES6 module bundler for JavaScript

 Rollup is a module bundler for JavaScript which compiles small pieces of code
 into something larger and more complex, such as a library or application. It
 uses the standardized ES module format for code, instead of previous
 idiosyncratic solutions such as CommonJS and AMD.
 ES modules let you freely and seamlessly combine the most useful individual
 functions from your favorite libraries. Rollup can optimize ES modules for
 faster native loading in modern browsers, or output a legacy module format
 allowing ES module workflows today.
 Node.js is an event-based server-side JavaScript engine.
