Ok this looks great!

I just realized I gave the wrong instructions though so we need to change https://github.com/babel/babel-preset-env/blob/master/data/built-in-features.js#L123 too

const es2016 = {
  "es7.array.includes.js": "Array.prototype.includes",
};

Updated the branch to include this change too, all tests seem fine too.

Nice work @roman-yakobnyuk!

yeah data/built-in-features.js is the hardcoded data and the other file is generated via npm run build-data but didn't want to make it too complicated - will merge once CI passes.

Oh yeah a tip: you can put Fixes #issue-number-here in the description/commit message and it will automatically close the corresponding issue. (I could of did this when merging but forgot)

Will keep that in mind for future, thanks!

Just so you're aware, this PR caused our config to break. It's easy to fix but I wonder if this could have been a minor server bump

I had no idea @skattyadz, I'm not sure why I had it originally and so I figured it was unnecessary (thus no reason for just a patch bump).

Can you explain the error and all that?
