Partial application

In simple terms, partial application involves taking a function that accepts several arguments, supplying some of these arguments, and returning a new function that only requires the remaining arguments. This is very similar to what currying does.

Currying transforms a function with multiple arguments into a sequence of functions, each accepting a single argument. This enables partial application naturally, as each function returned by a curried function can be considered a partially applied function.

The key difference between currying and partial application lies in their implementation and usage:

Currying is about transforming the function structure itself, turning a multi-argument function into a chain of single-argument functions

Partial application, on the other hand, does not necessarily change the function structure but reduces the number of arguments it needs by pre-filling some of them

Partial application can be particularly useful in scenarios...
