Decorating is simply wrapping one piece of code with another, thereby decorating it. A decorator (also known as a decorator function) can additionally refer to the design pattern that wraps a function with another function to extend its functionality. The concept of decorators is not new in JavaScript because higher-order functions are a form of function decorators. The TC39 class decorator proposal aims to solve this problem.
