What features are you thinking of? I hadn’t heard anything about TS types making their way into JS in any way (unless you count engines that can execute TS directly, but those just ignore the type syntax). That would be a massive change.

Hmm, I don’t think either of those warrants any concern about “TS features making their way into JS” or “overlapping syntax”.

The first one is removing a TS feature that failed to make its way into JS, and the second is about explicitly carving out a space in the syntax so that you can use TS (or Flow!) in JS codebases without being locked into any particular tooling.
