A list of a lot of the noop packages on NPM and their differences. If you find any more, please file an issue! If you need help deciding which one to use, just file an issue with your exact context and everything and we'll answer.
Note: noop5 is not included because it only works in TypeScript, and co-noop is not included because it's a generator function, and none is not included even though it's a noop, because it's meant for performance and not to be used as a noop.
