What are advanced generics in TypeScript?

Advanced generics in TypeScript allow for more flexible and reusable code by enabling type parameters, constraints, and utility types.

Can you give me an example of using generics with constraints?

Sure! Here's an example: function identity<T extends string | number>(arg: T): T { return arg; } This function only accepts strings or numbers.

What are some common use cases for generics?

Common use cases include creating reusable components, data structures like linked lists, and utility functions that work with various types.

How do utility types like Partial and Pick work with generics?

Utility types like Partial<T> make all properties of T optional, while Pick<T, K> creates a type by picking specific properties from T.
