question: what should be setting when using core-js v3

we had imported core-js and regenerator-runtime

import 'core-js/stable'
import 'regenerator-runtime/runtime'

// eslintrc.js
  "settings": {
    "polyfills": [
       ???
    ]
}

@amilajack I am using Webpack with Babel and @babel/preset-typescript. It doesn’t autodetect the core-js polyfills for me.

For example, I get this error: Promise is not supported in op_mini all compat/compat

Babel config goes in .babelrc, .babelrc.js, or a babel property in package.json.

Ah. Didn’t know it could be a property in package.json. Thanks for the info.
