The Array splice() method adds and/or removes array elements, overwriting the original array.

<!-- html element to place output -->
<p id="my_cars"></p>

Example 1:

// array
let cars = ['Lamborghini', 'Ferrari', 'Maserati', 'Alfa Romeo'];

// at position 2, add 2 elements
cars.splice(2, 0, 'Astin Martin', 'McLaren');

// output the array items to the HTML element
document.getElementById('my_cars').innerHTML = cars;

Example 2:

// array
let cars = ['Lamborghini', 'Ferrari', 'Maserati', 'Alfa Romeo'];

// at position 2, remove 2 elements
cars.splice(2, 2);

// output the array items to the HTML element
document.getElementById('my_cars').innerHTML = cars;

The way this works (see Syntax section below):

• The splice() method goes to a specified position in the array (in this case 2) and either adds or removes items

Example 1:

Lamborghini,Ferrari,Astin Martin,McLaren,Maserati,Alfa Romeo

Example 2:

Lamborghini,Ferrari

array.splice(index, howmany, item1, item2, etc.)

Parameter	Description
index	The position to add/remove items; negative value defines the position from the end of the array (required)
howmany	Number of items to be removed
item1, item2, etc.	New elements(s) to be added
