Minifiers

A minifier can reduce the size of a JavaScript file based on a certain configuration, for example by removes comments, making variable and function names smaller, removing whitespace, and so on. This allows us to have a much smaller bundle size and faster execution without sacrificing readability, while the JavaScript executes and behaves the exact same way.

For example, we can minify the compiled result we previously got after compiling our code with Babel.
