What are higher order functions? Put simply, higher order functions are functions that operate on other functions either by taking them as arguments or by returning them. This is what makes them “higher order” — they’re operating on a higher level than regular functions.
Why are they so cool? By passing functions as arguments or returning them as results, you can create more modular code that can be easily customized and adapted to different situations. This is a key principle of functional programming, which emphasizes the use of small, composable functions that can be combined in different ways to solve complex problems. Check out "Higher order functions" for all the details.
