![]() and the number of elements to be removedĪrray.splice(index, number of elements to be removed) Note: the Slice( ) method can also be used for strings.Īnd here is the splice syntax: //For removing elements, we need to give the index parameter, Here is the slice syntax: array.slice(from, until) The splice( ) method changes an array, by adding or removing elements from it. The slice( ) method copies a given part of an array and returns that copied part as a new array. Use negative numbers to select from the end of an array. ![]() If omitted, all elements from the start position and to the end of the array will be selected. ![]() An integer that specifies where to end the selection. Use negative numbers to select from the end of an array.Īrgument 2: Optional. An integer that specifies where to start the selection (The first element has an index of 0). The new item(s) to be added to the array.Īrgument 1: Required. 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. Splice() method can take n number of arguments:Īrgument 2: Optional. The splice() method changes the original array and slice() method doesn’t change the original array. The slice() method returns the selected element(s) in an array, as a new array object. The splice() method returns the removed items in an array. Returns: An array containing the extracted elements. If end is negative it is treated as "Math.max((array.length + begin),0)" as per spec (example provided below) effectively from the end of array. Last index for extraction but not including (default array.length). If begin is negative it is treated as "Math.max((array.length + begin), 0)" as per spec (example provided below) effectively from the end of array. Remove last element (start -> array.length+start = 3)Ĭonsole.log('Elements deleted:', array.splice(-1, 1), 'mutated array:', array) ![]() Console.log('Elements deleted:', array.splice(0, 1), 'mutated array:', array) ![]()
