I remember there being talk about Phaser 4 migrating to TypeScript so I'd be curious if that’s still going to happen.
You can already use TypeScript with Phaser and they extract all the jsdoc notation to TS bindings so in terms of making a game there wouldn't be much to gain from the framework itself transitioning, but it it would be nice to see them do that + start reinforcing it all with tests.
