What Is Partial Application?
Partial application is supplying a function with some but not all of its arguments to get back a new function that expects the rest. The provided arguments are captured, and the resulting function is called later with the remaining ones. It specializes a general function into a more specific one without rewriting it.
Why it matters
Partial application lets you pre-configure behavior and pass the resulting specialized function around, reducing repetitive argument passing. It pairs naturally with currying and higher-order functions.
