Jyoti Sachdeva explains the concept of higher-order functions and shares an example in Scala:

This is possible because functions are first-class value in scala. What does that mean?

It means that functions can be passed as arguments to other functions and functions can return other function.

The map function is a classic example of a higher order function.

Higher-order functions are one of the key components to functional programming and allows us to reason in small chunks at a time
