Removing Elements from an Array
One of the most common uses of the Splice method is to remove elements from an array. To do this, we can set the deleteCountparameter to the number of elements we want to remove, and omit the item parameters. Here is an illustration of how to remove elements from an array using specified index positions. Output In this example, we remove two elements starting from index 2 (i.e., the third and fourth elements), leaving us with an array of [ 23, 6, 23 ].
Inserting Elements into an Array
Another use case of the Splice method is to insert new elements into an array. To do this, we can set the deleteCount parameter to zero, and provide one or more item parameters representing the elements to be inserted. We also specify the startIndexparameter as the index where we want to insert the new elements. Output In this example, we insert two elements (i.e., 6 and 7) at index 2, shifting the existing elements to the right. The resulting array is [1, 2, 6, 7, 3, 4, 5].
Replacing Elements in an Array
The Splice method can also be used to replace existing elements in an array. To do this, we can set the start and deleteCountparameter to the number of elements we want to replace, and provide one or more item parameters representing the new elements to be inserted. Here's how you can replace 6, 3, and 323 with 'Go', 'Python', and 'JS', respectively: Output In this example, the splice method removes 3 elements starting from index 1, which are 6, 3, and 323. Then, it adds 'Go', 'Python', and '...
The splice()method is a powerful tool for working with arrays in JavaScript. It allows us to add, remove, and replace elements in an array with ease. By understanding the syntax and parameters of the Splice method, we can use it to solve a wide range of programming problems. While the splice()method is not the only way to manipulate arrays in JavaS...
