JavaScript Arrays

The splice() Method

The splice() method adds new elements to an array, and returns an array with the deleted elements (if any):

const fruits = ["Banana", " Orange", " Apple", " Mango"];
document.getElementById("demo1").innerHTML = "Original Array:<br> " + fruits;
let removed = fruits.splice(2, 2, " Lemon", " Kiwi"); 
document.getElementById("demo2").innerHTML = "New Array:<br>" + fruits;
document.getElementById("demo3").innerHTML = "Removed Items:<br> " + removed;

• The first parameter (2) defines the position where new elements should be added (spliced in).
• The second parameter (2) defines how many elements should be removed.
• The rest of the parameters ("Lemon" , "Kiwi") define the new elements to be added.
• The splice() method returns an array with the deleted items:
