TS takes one day to get going, which is one of the best things about it.

Stick to the 'basics' of TS, which are super general programming syntax structures and idioms - there's really nothing new you'll come across (maybe unions?) - so it's easy.

Then you can try some of the trickier things but frankly we don't use them that much.

You'll be up and running pretty quickly because you can mix your 'new' TS modules with old-school JS code no problem.

And then go from there.

I like TS because it's not some big new fancy paradigm shift: it's just typing, some other pragmatic things, and it works pretty well, very quickly.

It's the only tech I will actively evangelize as being 'the thing you need if you use JS' type thing.
