Arrays.isEmpty()

Syntax

function isEmpty(iterable: Iterable<unknown> | HasLength | HasSize): boolean

Example

import { Arrays } from 'potence';

Arrays.isEmpty([]);         // -> true
Arrays.isEmpty([1, 2, 3]);  // -> false
Arrays.isEmpty(new Set());  // -> true

Remarks

If the iterable has a length or size property, this function simply checks whether its value is 0. If the iterable has neither, this function checks whether its iterator returns any elements. This means that the time complexity of this function is O(1) for both array-likes and other iterables.

Compare Arrays.isNotEmpty().
