There already exists a Await or Awaited utility type in Typescript that does hack #1 but it still is a cool example to show Infer. I liked that

@gryg666 5 месяцев назад

Thank you very much for the last one. Comming to typescript word was hell without it.

May I ask the extension of VSCode you use to display the blur text "newTab" in line 8 in 6:40 minutes? Thanks!

@CoderOne 5 месяцев назад

What do you mean by the blur text?

Hi Islem, hope you are doing well, may i ask you from where have you bought your chair,,, i am from (19 lol) as well

#2 Why not just use type Tab = 'dashboard' | 'home' | 'about'; function switchTab(newTab: Tab) {} ? Is there a difference ?

@remmoze 5 месяцев назад

when you need to add another tab, you have to modify multiple places instead of one and it's easier to make human mistakes when you separate your logic

@CoderOne 5 месяцев назад

Adding to what @remmoze said, We should use an Object instead of a Type tab = "..." because an object can be used programmatically (at runtime) to access different tabs and a type cannot, a type, can only be used to determine the type at compile time and to help us write better code.

@coolemur976 5 месяцев назад

@@remmoze Type is defined in single place tho in example I've provided... Furthermore, in video you have object which has key-values with repetative keys and values ( dashboard: "dashboard" )

@coolemur976 5 месяцев назад

@@CoderOne Isn't compile time type check enough tho for tab switch (or is this just in this example)? And isn't it better to pass simpler type to a function - simple string instead of object? Why is it better to pass object than primitive type to a function ? Doesn't that just make fn overcomplicated in this case? I am assuming here that switchTab fn implementation would be case by literal string, which would make selected tab active and some content displayed...

I use componentProps…

I like this video but these aren't "hacks" They're type level typescript using the functionality as intended. Lesser known functionality, but still used as intended here. But maybe the title is just for the algorithm. I just don't want people thinking this isn't how its meant to be used but it somehow accomplishes this outcome. Because in reality, this is how its meant to be used at an advanced level.
