Add rule "Use native Intl.NumberFormat to format numbers"

[utarwyn]

There's no need to use a library to display formatted numbers in a recent browser (even IE 11 seems to be supported!). It seems possible to use Intl.NumberFormat for that use case.

Maybe we can also use Intl for other use cases? You can adapt the idea to what it looks better for you.

Check MDN docs and Can I use table

A few librairies which format numbers: https://numbrojs.com/ and https://github.com/gastonmesseri/numerable and http://numeraljs.com/ and https://formatjs.github.io/ and https://github.com/Mottie/javascript-number-formatter
