Was reading mapped types in the Typescript docs but I did not get it. This video helped a lot. Thanks!

OMG dude, this hands down feels like PREMIUM content, holy molly! You're by far the best Typescript YouTuber outthere. I'm already sharing this channel with a bunch of co-workers. I genuinely hope your channels continues to grow!

i like how to the point all the lessons are, he just gets straight to the point and does it so quick and neat, i really like this, usually tut instructors do unnecessarily long lessons that fill you with all kinds of useless info but this guy just gives you what you need and moves on love it

Really solid, succinct explanation, and the gradual progression of increasing the generality of the example type definition was extremely helpful. Thank you!

[LilahAugust]

This helped way more than any of the much longer videos I watched that tried to explain this. Thank you!!!

Great video! Microsoft Should have creators like yourself do videos for their pedantic handbook which I’m re reading and some of it is so overdone

The link in the description for the "Lookup" is not pointing to an available video :)

Hey buddy! Thanks for your awesome videos! Maybe you could consider to make the font size bigger when coding so it'll be readable on mobiles as well even for the 40+ folks as am I. Thanks a lot!

Very useful video. Thanks a lot Basarat. Would this be possible using interfaces too, instead of types?

[DanishAnton]

Great series. Was getting frustrated with Typescript but your videos helped. FYI, the link to keyof Operator in your description is returning Video Unavailable.
