![]() If Argument(2) is less than 0 or equal to NaN, it is treated as if it were 0.Ĭonsole.log(array6.splice(2,-5,"Hello")) Ĭonsole.log(array6.splice(3,NaN,"World")) If Argument(1) is NaN, it is treated as if it were 0.Ĭonsole.log(array5.splice(NaN,4,"NaN is Treated as 0")) shows, returned removed item(s) as a new array object.Ĭonsole.log(arra圓.splice(2,1,"Hello","World")) The new item(s) to be added to the array. And if not passed, all item(s) from provided index will be removed.Īrgument 3…n: Optional. If set to 0(zero), no items will be removed. An integer that specifies at what position to add /remove items, Use negative values to specify the position from the end of the array.Īrgument 2: Optional. The splice() method can take n number of arguments:Īrgument 1: Index, Required. The splice() method changes the original array and slice() method doesn’t change the original array.ģ. The splice() method returns the removed item(s) in an array and slice() method returns the selected element(s) in an array, as a new array object.Ģ. Examples Remove 0 (zero) elements from index 2, and insert "drum" Remove 0 (zero) elements from index 2, and insert "drum" and "guitar" Remove 1 element from index 3 Remove 1 element from index 2, and insert "trumpet" Remove 2 elements from index 0, and insert "parrot", "anemone" and "blue" Remove 2 elements from index 2 Remove 1 element from index -2 Remove all elements after index 2 (incl.) Specifications SpecificationĮCMAScript Latest Draft (ECMA-262) The definition of '' in that specification.ĮCMAScript 2015 (6th Edition, ECMA-262) The definition of '' in that specification.ĮCMAScript 5.1 (ECMA-262) The definition of '' in that specification. If the specified number of elements to insert differs from the number of elements being removed, the array's length will be different at the end of the call. If no elements are removed, an empty array is returned. If only one element is removed, an array of one element is returned. Return valueĪn array containing the deleted elements. If you do not specify any elements, splice() will only remove elements from the array. Optional The elements to add to the array, beginning from start. In this case, you should specify at least one new element (see below). If deleteCount is 0 or negative, no elements are removed. ![]() If deleteCount is omitted, or if its value is equal to or larger than array.length - start (that is, if it is equal to or greater than the number of elements left in the array, starting at start), then all the elements from start to the end of the array will be deleted. deleteCount Optional An integer indicating the number of elements in the array to remove from start. If the absolute value of start is greater than the length of the array, it will begin from index 0. If negative, it will begin that many elements from the end of the array (with origin -1, meaning -n is the index of the nth last element and is therefore equivalent to the index of array.length - n). If greater than the length of the array, start will be set to the length of the array. Parameters start The index at which to start changing the array.
