Several of you asked me why TypeScript chose Go instead of C#, and what that decision implies about Microsoft's commitment to C# and .NET.
See

TL;DR nothing has changed.

β¨What a dream come true!β¨ The co-creator of @typescript himself, @ahejlsberg, took some time to look at the Doom project!
We also had a chance to chat about other TypeScript topics more broadly - and that video will go live in a few days!
DREAM. COME. TRUE.π

Doom now runs in @typescript types. What a journey this one's been.
Please, for the love of god, do not abuse this flag. It's not here for aesthetic reasons to let you write paths that are actually misleading.
Blue pill: Correct and consistent mental model that requires one step of understanding
Red pill: Easy mental model that yields inconsistent or incorrect results
Me to JS devs: ... did you just take both pills?

Nice writeup of TypeScript's new ability to infer type predicates from @mattpocockuk. I'm 0% surprised that Matt beat me to writing a blog post about this :)
I really can't believe they added it.

My wild idea to improve the carbon footprint of @climatearena is that if you take an umbrella to stay dry instead of driving to the arena, they don't make you throw it away when you get there. Thoughts?

`assertUnreachable` is an advanced TypeScript technique popularized in a @StackOverflow post by @SeaRyanC (from the @typescript team). So we thought it'd be cool for Ryan to return to the channel to talk about it!
