Better browserslist

Why?

Depending on your babel setup, you won't have the same bundle same at the end. A big part of every builds are transpiled such as arrow functions. But nowadays, a lot of browsers supports those features.

Here is an example of different transpilations of a same input file with different targets in their babel configuration and the related coverage of this target among every browsers based on browserslist.

How to use

const { modern, regular, regular_strict, not_modern, not_regular, old, oldest, defaults } = require('better-browserslist');

You can use one of those config in your own babel config.

old and oldest are respective aliases to regular_strict and not_regular

I recommend using modern, old or older.
