// discuss at: https://locutus.io/php/rsort/
// original by: Kevin van Zonneveld (https://kvz.io)
// revised by: Brett Zamir (https://brett-zamir.me)
// improved by: Brett Zamir (https://brett-zamir.me)
// note 1: SORT_STRING (as well as natsort and natcasesort) might also be
// note 1: integrated into all of these functions by adapting the code at
// note 1: https://sourcefrog.net/projects/natsort/natcompare.js
// note 1: This function deviates from PHP in returning a copy of the array instead
// note 1: of acting by reference and returning true; this was necessary because
// note 1: IE does not allow deleting and re-adding of properties without caching
// note 1: of property position; you can set the ini of "locutus.sortByReference" to true to
// note 1: get the PHP behavior, but use this only if you are in an environment
// note 1: such as Firefox extensions where for-in iteration order is fixed and true
// note 1: property deletion is supported. Note that we intend to implement the PHP
// note 1: behavior by default if IE ever does allow it; only gives shallow copy since
// note 1: is by reference in PHP anyways
// note 1: Since JS objects' keys are always strings, and (the
// note 1: default) SORT_REGULAR flag distinguishes by key type,
// note 1: if the content is a numeric string, we treat the
// note 1: "original type" as numeric.
// example 1: var $arr = ['Kevin', 'van', 'Zonneveld']
// example 1: rsort($arr)
// example 1: var $result = $arr
// returns 1: ['van', 'Zonneveld', 'Kevin']
// example 2: ini_set('locutus.sortByReference', true)
// example 2: var $fruits = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'}
// example 2: rsort($fruits)
// example 2: var $result = $fruits
// returns 2: {0: 'orange', 1: 'lemon', 2: 'banana', 3: 'apple'}
