Package Exports

is-empty-iterable

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-empty-iterable) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

const isEmptyIterable = require('is-empty-iterable');

isEmptyIterable([]);
//=> true

isEmptyIterable(new Set([1, 2]));
//=> false
