isSortedBy<
ElementType>(iterable:IterableResolvable<ElementType>,comparator:CompareByComparator<ElementType>):boolean

comparator | CompareByComparator<ElementType> | - |
Returns
boolean

Example
import { ascNumber, isSortedBy } from '@sapphire/iterator-utilities';
assert(isSortedBy([1, 2, 2, 9], ascNumber));
assert(!isSortedBy([1, 2, 2, 9], ascNumber));
assert(isSortedBy([0], () => true));
assert(isSortedBy([0], () => false));
assert(isSortedBy([], () => true));
assert(isSortedBy([], () => false));
