As someone who is learning TypeScript, I have been exploring various sources and courses in order to enhance my skills. However, I have encountered a challenge regarding how to make the compiler prompt for arguments when defining a typed function.
Let's consider a straightforward example: imagine I have a function that expects two strings, firstName and lastName, and should return their concatenation:
type FuncType = (firstName: string, lastName: string) => string;
const getFullName: FuncType = () => "";
It is evident that the function definition here is incomplete. Nevertheless, at this stage of defining the function, I would have expected the compiler to notify me of the missing parameters (firstName and lastName) as they are clearly required based on the type FuncType.
However, that is not happening. Can anyone guide me on what I might be overlooking?
