Type Inference from Function Signatures and Arrays
Learn TypeScript's type inference for function signatures, arrays, and three standard conditional types: Exclude, Extract, and NonNullable.
We'll cover the following
In the same way that we can define inferred types based on object properties, we can also infer types based on function signatures.
These inferred types can be inferred from either the function arguments or from the function return type. Let’s take a look at an example of this:
