@pvorona/noop

A tiny no-op function.

Install

npm i @pvorona/noop

Usage

import { noop } from '@pvorona/noop';

element.addEventListener('scroll', handler ?? noop);

Another common use: default optional callbacks.

import { noop } from '@pvorona/noop';

export function withFinally(run: () => void, onFinally: () => void = noop) {
  try {
    run();
  } finally {
    onFinally();
  }
}

API

noop(): void

Does nothing and returns void.

Notes:

• You can pass noop where a callback is required but you have nothing to do.
• In JavaScript, extra arguments are ignored, so noop is also safe as a fallback for many event handler types.

Example:

import { noop } from '@pvorona/noop';

const onError: (e: unknown) => void = noop;
