The only information you have is that any type could be produced if you pass in a string. As a result, when the function returns, you lose the information about what that type was. When you use 'Any,' the function accepts any kind for the type of arg. You could either provide the identity function with a specific type or the identity function with any type. The identity function is a function that returns whatever is sent in as a parameter.

You will now understand why you need TypeScript Generics, with an example.Ĭonsider the below code without generics. You can construct generic classes, generic methods, and generic functions with TypeScript. Only related types of things are found in the generics collections. For example, generics make use of a separate type variable to represent types. You must write a type parameter between the open () and close (>) brackets in generics to build strongly typed collections. Generic functions have the same type as non-generic functions, with type arguments specified first, as in function declarations. The type variable in TypeScript is used to denote types and uses generics. Type safety is provided via generics without sacrificing performance or efficiency.

Generics ensure that the software is both adaptable and scalable over time. It enables users to consume these components while also using their own kinds. Rather than working with a single data type, it builds a component that can interact with various data kinds. TypeScript Generics is a tool for creating reusable components in TypeScript.
