It is one of the best-known principles of software development and observing it is very important when building an application or writing code in general.

[Johny @flyingBird520]

Higher-order components (HOCs) in React were inspired by higher-order functions in JavaScript. A HOC is an advanced technique for reusing logic in React components. It is a pattern created out of React’s compositional nature.

[Johny @flyingBird520]

HOCs basically incorporate the don’t-repeat-yourself (DRY) principle of programming, which you’ve most likely come across at some point in your career as a software developer.
