Learn webpack!

Webpack (stylised webpack) is an open-source JavaScript module bundler. It is a module bundler primarily for JavaScript, but it can transform front-end assets like HTML, CSS, and images if the corresponding plugins are included. Webpack takes modules with dependencies and generates static assets representing those modules.Webpack takes the dependencies and generates a dependency graph allowing web developers to use a modular approach for their web application development purposes. It can be used from the command line, or can be configured using a config file which is named webpack.config.js. - read more on Wikipedia
