    asyncNoop es-toolkit

    A function that asynchronously does nothing.

    const promise = asyncNoop();
    Info

    noop function

    If you need a function that synchronously does nothing, use the noop function which immediately returns void.

    Usage

    asyncNoop()

    Use asyncNoop when you need to fill a placeholder or use as a default value where an asynchronous function is required. It returns a Promise that resolves to undefined.

    import { asyncNoop } from 'es-toolkit/function';

// Example using as a default value
interface Props {
  fetchData?: () => Promise<void>;
}

function MyComponent({ fetchData = asyncNoop }: Props) {
  const handleFetchData = async () => {
    // fetchData is always a function, so it's safe to call
    await fetchData();
  };

  handleFetchData();
}

// Example of direct invocation
asyncNoop();
// Returns: Promise<void>

await asyncNoop();
// Returns: undefined

    Returns

    A Promise that resolves to undefined.

    Promise<void>
