[Webpack 2] Optimize React size and performance with Webpack production plugins

You can fine tune several Webpack plugins to make your bundle as small as it can is for your specific application. However there is a few things you can does for pretty much every application to make it smaller and run faster. In this lesson we'll combine several webpack plugins to optimize things for a React application (this is also applicable F or non-react applications as well).

First we need to modify the Prod scripts from:

" Build:prod " " Webpack--env.prod-p ",

To:

" Build:prod " " Webpack--env.prod ",

Help methods:
