TypeScript Weekly

Issue #169 — April 29, 2021

Hi there!

I’m super stoked to announce my new TypeScript course:

Watch the Course

I’ve put a lot of thought, time, and effort into this course, and I’m really proud of how it turned out. Go check it out and learn a thing or ten about TypeScript!

Cheers,
Marius
