Update Babel to support new TypeScript 3.7.2 syntax features
See original GitHub issueIs your proposal related to a problem?
When updating my projects TypeScript version to the new 3.7.2 and trying to use the new syntax, such as optional chaining:
foo?.bar()
I get an error during runtime saying that Babel does not support this feature:
Support for the experimental syntax ‘optionalChaining’ isn’t currently enabled Add @babel/plugin-proposal-optional-chaining (https://git.io/vb4Sk) to the ‘plugins’ section of your Babel config to enable transformation.
Describe the solution you’d like
It would be nice if the Babel config made by CRA would install these new features. I do not want to have to eject to customize my Babel config.
Describe alternatives you’ve considered
I’ve tried installing the Babel plugin as described here with no luck: https://babeljs.io/docs/en/babel-plugin-proposal-nullish-coalescing-operator

I’m still waiting for a CRA release to start using TS 3.7 for all our projects (monorepo).
Dupe of #7431. We’ll be releasing support in the next few days.
