![]() ![]() We set the deleteCount parameter to 2 because we wanted to remove two elements from the array. In this example, we started modifying the “fruits” array from index 1 (i.e., the second element in the array). We can do this using the splice method as follows: Let’s say we have the same “fruits” array as in Example 1, and we want to remove two elements from it. The output shows the updated “fruits” array with the added elements.Įxample 2: Removing elements from an array using the splice method We then added two elements ‘grapes’ and ‘mango’ to the array using the third parameter. We set the deleteCount parameter to 0 because we didn’t want to remove any elements from the array. Let fruits = Ĭonsole.log(fruits) // Output: Let’s say we have an array called “fruits” with three elements, and we want to add two elements to it. Example 1: Adding elements to an array using the splice method Let’s consider an example to understand how the splice method works. ![]() You can add one or more elements using this parameter.Īrray.splice(start, deleteCount, item1, item2, …) The elements to add – The elements to add to the array.The number of elements to remove – The number of elements to remove from the array.The start index – The index at which to start modifying the array.The splice method is a built-in JavaScript method that allows you to modify an array by adding or removing elements from it. In this article, we will discuss how to work with the JavaScript array splice method. Splice is a powerful method that can be used to add, remove, and replace elements from an array. It offers various array methods to manipulate and modify arrays, one of which is the splice method. is a versatile programming language that is widely used in web development.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.
