TypeScript utility types you need to know

#typescript #javascript #webdev

Pure knowledge, more in a limited time than anyone else

There's also the Uppercase<T> and Lowercase<T> which can perform case changes on string literal types!

I had to use the Parameters utils class, because I had a package that DID export out the type that it accepts.. but then there was a plugin that extended that type, but THEY didn't export out the type..
Thankfully TS was cleaver enough that because I was importing the plugin, that imported the type, so the function could get the "end result" of what was allowed..
I was VERY impressed it worked..

Great job the TS team.

This is why I prefer Types instead a interface

I'm more impressed how you instantly wrapped the type with "<" and ">" characters. What extension are you using to do that without selection first?

This content is awesome.
This would’ve been so helpful when I was beginning to learn Typescript

I feel like useState's state should be "readonly" by default, I mean, React should make it readonly by default right? Is there ever a scenario where it's NOT readonly?

Yes, knew all of these. What I don't know is how you got your editor to wrap your generics properly for you. I need that.
