Currying

The Definition

Currying is the process of dividing a function with multiple parameters into separate functions for each parameter.

A function can be curried when we provide it with fewer arguments than it originally needs and assign this incomplete call to a new let binding.

Now, we only need to pass the remaining arguments to the new function.

Note: Passing more arguments than the function actually has, will produce a compile-time error. Currying only works when we provide an incomplete number of arguments.
