How to Delete an Index from an Array in JavaScript?

Estimated read time 1 min read

In JavaScript, you can delete an index from an array using the splice() method. The splice() method allows you to modify an array by adding or removing elements.

To remove an index from an array, you can simply use the splice() method with the index of the element you want to remove and the number of elements to remove. Here’s an example code snippet:

let myArray = [1, 2, 3, 4, 5];

myArray.splice(2, 1);

console.log(myArray);

In the above code, the splice() method is used to remove the element at index 2 (which is the number 3) from the myArray array. The second argument passed to splice() specifies that only one element should be removed.

The result of this code snippet will be an array that looks like this:

[1, 2, 4, 5]

Note that the splice() method modifies the original array, so make sure to use it carefully.
