Abstract
In the previous chapter we saw how higher-order functions help us as a developer to create abstraction over the common problems! It’s a very powerful concept as we learned. We have created our sortBy higher-order function to showcase a valid and relevant example of the use case. Even though the sortBy function is working on the basis of higher-order functions (which is again the concept of passing functions as arguments to the other functions), it has something to do with yet another concept called Closures in JavaScript.
