This option is no longer `@babel/preset-env` specific since v7.13.0
Opera Mobile has relaunched for Android using Chromium but the compatibility data still thinks lots of features are unsupported:
```
The es-shims polyfill added the following polyfills:
Array.prototype.every { "opera_mobile":"73" }
Array.prototype.indexOf { "opera_mobile":"73" }
Array.prototype.keys { "opera_mobile":"73" }
Date.now { "opera_mobile":"73" }
Function.prototype.name { "opera_mobile":"73" }
Object.entries { "opera_mobile":"73" }
String.prototype.split { "opera_mobile":"73" }
String.prototype.trim { "opera_mobile":"73" }
```
See related issues:
browserslist/browserslist#766
babel/babel#15711
See core-js on GitHub: https://github.com/zloirock/core-js
Although this polyfill is required for feature complete Error support, we don’t use the `.cause` property yet
```
The es-shims polyfill added the following polyfills:
es.error.cause { "android":"61", "chrome":"61", "edge":"16", "firefox":"60", "ios":"10.3", "opera":"48", "safari":"10.1", "samsung":"8.2" }
```
Although this polyfill is required for bug-free `new URL('http://x', undefined)` in Safari versions < 14 with an `undefined` base, we don’t use it:
```
The corejs3 polyfill added the following polyfills:
web.url { "chrome":"61", "edge":"16", "ios":"10.3", "opera":"48", "safari":"10.1", "samsung":"8.2" }
web.url-search-params { "chrome":"61", "edge":"16", "ios":"10.3", "opera":"48", "safari":"10.1", "samsung":"8.2" }
```
Although these polyfills are required to iterate DOM collections, we always use `Array.from()` so don’t need them:
```
The corejs3 polyfill added the following polyfills:
es.array.iterator { "chrome":"61", "opera":"48", "samsung":"8.2" }
web.dom-collections.iterator { "chrome":"61", "edge":"16", "ios":"10.3", "opera":"48", "safari":"10.1", "samsung":"8.2" }
```
For example, polyfills to fix unhandled empty space characters in ES5 `''.trim()` that would be removed in ES2015

This PR adds the Babel polyfill provider core-js via:
https://www.npmjs.com/package/babel-plugin-polyfill-corejs3
This is part of a two spike series:
Findings
Lots more polyfills are added by core-js when compared to ES shims in #4301
We also have lots more unwanted bug fixes:
Array.prototype.frompolyfill because the type being iterated is unknownArray.prototype.includespolyfill to avoid bugsError.prototype.causepolyfill to avoid bugsURLconstructor polyfill to avoid bugsIncluding an overwhelming amount of polyfills to patch various browser APIs in already-supported features:
For example, Safari 12.1 updated
''.trim()to include revised empty space characters:paulmillr/es6-shim#354 (comment)
Similarly, versions below Firefox 102 handled
[].includes()with sparse arrays incorrectly:https://bugzilla.mozilla.org/show_bug.cgi?id=1767541
Global polyfills
This PR uses
core-jsrather thancore-js-puresince lots of polyfills are missed due to:usage-purehas incorrect optimization logic babel/babel-polyfills#166Remaining issues
es6-modulebut Babel disagrees@rollup/plugin-commonjsadds ES module wrappers to polyfills@rollup/plugin-babeladds helpers to avoid ES module wrappersdist/govuk/node_modulesnotdist/govuk/vendorAutomatic polyfills
When Babel was added we chose "transforms only" without polyfills (see decision record)
This PR ensures early investigations aren't lost for:
Decision record implications
Since Babel with "transforms only" silently skips polyfills, we noted that care must be taken:
This spike PR ensures:
i.e. Support for both polyfills and protection from missed polyfills all-in-one
