// discuss at: http://locutus.io/php/array_splice/
// original by: Brett Zamir (http://brett-zamir.me)
// input by: Theriault (https://github.com/Theriault)
// note 1: Order does get shifted in associative array input with numeric indices,
// note 1: since PHP behavior doesn't preserve keys, but I understand order is
// note 1: not reliable anyways
// note 1: Note also that IE retains information about property position even
// note 1: after being supposedly deleted, so use of this function may produce
// note 1: unexpected results in IE if you later attempt to add back properties
// note 1: with the same keys that had been deleted
// example 1: var $input = {4: "red", 'abc': "green", 2: "blue", 'dud': "yellow"}
// example 1: array_splice($input, 2)
// returns 1: {4: "red", 'abc': "green"}
// example 2: var $input = ["red", "green", "blue", "yellow"]
// example 2: array_splice($input, 3, 0, "purple")
// returns 2: []
// example 3: var $input = ["red", "green", "blue", "yellow"]
// example 3: array_splice($input, -1, 1, ["black", "maroon"])
// returns 3: ["yellow"]
// test: skip-1
