Maybe the most insightful 3 minutes of TypeScript in my life

quickly becoming my favorite "programming tutorial" genre channel. The value to time ratio is insane

[alemaolonghi]

Matt, you are the real Wizard of TS .... \, , /

These videos are gold and especially bullshitless. Other YouTubers often convey the same amount of information in a 15 minutes tutorial.

The whole time I was watching this I kept saying "ohhhh my god" - absolutely unreal video

[himbary]

Nice one, I didn‘t know about Extract and NonNullable

[pupfriend]

those tips about getting parameters and return types from external libraries is great.

I liked your tweet about them being the "gateway drug" to type level programming!

I wish there was a plugin for my IDE that would look at what I'm doing and say "There's a built-in utility type that does this, you should use it". Because I forget about some of these

I don't know why you have so few views, the videos are pure gold

I learned about utilities like 5 months ago and man… whoever keeps creating this stuff, good shit

[SpaghettiRealm]

Been using typescript for a long time and did not know about most of these! 🔥

Never looked back when I first came across TypeScript.

[IceTank]

Thank you you TypeScript wizard. I wish I had known of these sooner.
