![]() ![]() Simply use the splice method and pass it additional arguments to add your element in the index you specified. In this post, we learned how to add an item to a specific index in an array in JavaScript. It has three arguments including the start index, delete count. Now let's look at the full code example: const element = "element" Ĭonsole.log(array) Conclusion Interview Response: The splice() method is used to add, remove, or replace elements in an array. We don't want to delete anything, so we can pass 0 as the second argument.Īnd we want to add our element, so we can pass element as the third argument.Īs a result, our usage of the splice method will look like this: array.splice(3, 0, element) We want to start at the 3rd index so we can pass 3 as the first argument. Knowing this, you can use Function.apply to pass the array as the arguments list. The splice method can take 3 arguments, the first one is the index you want to start from, the second one is the number of elements you want to remove, and the third one is the element you want to add. Those arguments will all be added to the array. You can do that by using the splice method. Now let's say you want to add it to the 3rd index of the array. How to add an item to a specific index in an arrayįirst, let's start with our example element and array: const element = "element" In this post, we'll learn how to add an item to a specific index you want in the array in JavaScript. However, what if you want to add an element to a specific index in an array? The XSP library contains classes that access the browser context.When you are working with an array and want to add an element, it is easy to add it to the start and end of an array, there are built-in functions for that. Represents common mathematical values and functions. Gets the string representation of an Array object. Gets the string representation of an Array object taking into account the host locale.
