Seems like babel does not provide polyfill? Because Number.isNan is ES6 feature and in disaplace.js it is not changed

Styles were fixed, but what to do with Number.isNan polyfill?
How do you usually proceed guys? :)
1) manual polyfill
2) import 'core-js/es6/number';
3) etc

thanks for your investigation. IE doesn't support Number.isNaN, so yeah perhaps we need to polyfill it.
I will take a look today later.

I was trying to use https://babeljs.io/docs/en/babel-plugin-transform-runtime,
it will add polyfills automatically only when needed (based on browsers from babel-present-env).
But, that's something which depends on require or import - we don't support it ¯\_(ツ)_/¯

I see 2 ways:
1) ignore it by eslint-disable-next-line
2) add https://polyfill.io/ or properly configure https://babeljs.io/docs/en/babel-polyfill

currently, I'd prefer the first option. Any other thoughts?

as @drpal mentioned somewhere in other tasks, it is quite costy to add polyfills in such cases, because they will be added to all separate files and we can handle duplication while we transpile each file separately

Nice. I think this fine for now.

@m1r1k & @ApacheEx - You are correct. Right now we don't have a solid plan for how we can handle polyfill support. If you want to open a followup where we can discuss an approach that would be wonderful.
