    is-empty-iterable

    Check if an Iterable is empty

    More efficient than Array.from(iterable).length, as it only iterates the first item, which can make a big difference for dynamic iterators, like a Generator doing an expensive operation.

    Install

    $ npm install is-empty-iterable
    

    Usage

    import isEmptyIterable from 'is-empty-iterable';
    
    isEmptyIterable([]);
    //=> true
    
    isEmptyIterable(new Set([1, 2]));
    //=> false

    API

    isEmptyIterable(iterable)

    Returns a boolean.
