TypeScript Weekly

Issue #183 — February 6, 2022

Hi there! 👋

This is the first issue of TypeScript Weekly in 2022. Welcome back if you've been with us last year already, and welcome aboard if you subscribed recently.

I took a break from the newsletter in January, but now we're back in full force. I thought we'd start the year by looking back at the most popular links from 2021, so I've compiled a list of the 10 most clicked posts from last year's issues.

There's lots of good content and helpful advice in these posts, I hope you find them useful. Enjoy!

Cheers,
Marius
