The noop function is a utility function that does nothing and simply returns undefined. You can use it in situations where you need to pass a function as an argument, but don't actually need any functionality to be executed. Here is an example:

function performAction(actionFunc) {
  actionFunc();
}

performAction(noop); // will execute performAction, but nothing will happen inside of it

Note that noop is simply an alias for () => undefined, so you could define it yourself as a stand-in if preferred:

const noop = () => undefined;
