Also, currently, if you run babel “out of the box”, it does absolutely nothing. It doesn’t even deem it worthy to warn you that “hey, may be you should include some presets or plugins maybe”. It just outputs whatever you input in.
God forbid you forget to install it the recommended way (i.e. with
babel-preset-latest, as advertised on the site). Why not include this preset with the default installation, is truly, really beyond me.
