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.

Type: Iterable
