The splice method also works well when looking to remove values from an array by index. If deleteCount is omitted, or if its value is larger than array.

If deleteCount is 0 or negative, no elements are removed. The above example may seem a little confusing because of all of the operations that took place.

Array.prototype.splice()

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone and send us a pull request. If greater than the length of javascript replace item in array array, actual starting index will be set to the length of the array. If negative, will begin that many elements from the end of the array with origin -1 and will be set to 0 if absolute value is greater than the length of the array. If deleteCount is omitted, or if its value is larger than array. If deleteCount is 0 or negative, no elements are removed. In this case, you should specify at least one new element see below. Optional The elements to add to the array, beginning at the start index. If you don't specify any elements, splice will only remove elements from the array. Return value An array containing the deleted elements. If only one element is removed, an array of one element is returned. If no elements are removed, an empty array is returned. Description If you specify a different number of elements to insert than the number you're removing, the array will have a different length at the end of the call.

If greater than the length of the array, actual starting index will be set to the length of the array. If no elements are removed, an empty array is returned. Return value An array containing the deleted elements. Something to pay close attention to is that the splice method acts directly on the array. If deleteCount is 0 or negative, no elements are removed. In this case, you should specify at least one new element see below.
