In this case, you should specify at least one new element (see below). If deleteCount is 0 or negative, no elements are removed. However, if you wish to pass any itemN parameter, you should pass Infinity as deleteCount to delete all elements after start, because an explicit undefined gets converted to 0. If deleteCount is omitted, or if its value is greater than or equal to the number of elements after the position specified by start, then all the elements from start to the end of the array will be deleted. This is different from passing undefined, which is converted to 0.Īn integer indicating the number of elements in the array to remove from start.
