Arrays.isNotEmpty()

Syntax

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

Example

import { Arrays } from 'potence';

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

Remarks

If the iterable has a length or size property, this function simply checks whether its value is not 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.
