Higher-order component

Higher-order component is a function that takes a component as an argument and returns a new component with some additional functionality. It's a powerful technique for reusing component logic across multiple components, popularized by the React library but also used in other frameworks like Vue and Angular.

How to use it in a sentence

"I'm going to write a higher-order component to handle authentication for all our protected pages. That way we don't have to duplicate the auth checking logic in every component."

"Looks like the new intern got a little higher-order component happy - now there's so many layers of abstraction, I can't even tell what the actual UI is supposed to do anymore!"
