higher-order functions, function types, generic callbacks
In TypeScript (or JavaScript), you can receive a function as a parameter by specifying it as a type in the function signature. Here's how you can do it:
Specify the type of the function parameter, including its arguments and return type.
You can define the function type as an alias for better readability and reuse.
If the function you're passing might have optional arguments, you can define them in the type.
A common use case for functions as parameters is callbacks, especially in asynchronous programming.
