@@patfre auch! was a funny way to say the content is great and well explained but still generics are hard and verbose no matter what. Will be healthy a pole to show how many devs use generics in his job. Also if an employer doesn't select you because you don't use a specific content, well, that is not the place.

@@jotasenator the whole point of generics is the make thing generic, they are very helpful in making things type safe especially with how much TS allows you to do, I just used it today to make my code simpler and cleaner and not be 100 lines of repeated code. Also the thing about companies is they want safe and reliable code that follows best practices a lot so they can absolutely deny you for something like this if your 100% not willing to follow their practices with the code

As someone who has been anxious even when seeing cryptic type notations, this lesson is almost like a therapy session. For me, adding just after writing the function name make sense than coming back to it after annotating arguments. It reads like "this function / class is meant to work with these types".. Thank you!

Wow this video shed a ton of light on some of the confusing pieces around generics for me. The content was so well put together and with the real life example with usages in react itself it really drove the point home from your early examples of generic benefits and when ti use them. Amazing way to teach these concepts. Thanks! Subscribed.

Why is the type parameter ( "") after the function name or type name necessary? I'm guessing it's just for better performance of the TS compiler. It seems the input parameter type(s) (including the sequence in which they appear) and the output type are sufficient information to determine the relationships that need to be codified. I'm grateful for your video. The statement that "generics are specifications of codifying relationships between parameter and output types" is excellent and did make it easy to understand generics.

@ExiledDelver11 ай бұрын
you mentioned not to have "any" in your first example you returned => return [input.toUpperCase()] and said if you have an any this is no good since a number cant use the toUpperCase, wouldnt a generic do identically the same thing? const someFunc = (input:T):T[] => return[input.toUpperCase()] is this not the same as any?

How do I use generics in some generic component like Table, when I need the id property, for filter let's say... in that case Typescript complains that can't find the id on T type, so I must add intersect with & { id: string }, so I can help Typescript to infer the id type.
