What are higher-order functions, and why should anyone care?  ↦

“Higher-order function” is one of those phrases people throw around a lot. But it’s rare for anyone to stop to explain what that means. Perhaps you already know what a higher-order function is. But how do we use them in the real world? What are some practical examples of when and how they’re useful? Can we use them for manipulating the DOM? Or, are people who use higher-order functions showing off? Are they over-complicating code for no good reason?
