[kormanowsky]

Node.js now supports TypeScript (see https://nodejs.org/api/typescript.html). Adding support for it in sitespeed/browseritime scripts.

Hi @kormanowsky thanks, could you also please add a typescript version of a script and a test that runs in one of the GitHub actions https://github.com/sitespeedio/browsertime/tree/main/.github/workflows ? That helps me make sure the support isn't broken,

Hi @soulgalore
Sure, will add a sample script and a test soon

And I have a question — what should we do with failing checks? They don’t seem to fail because of my changes..

Added tests @soulgalore

@soulgalore could you please restart the tests?
