Answer 2

You can use unshift(), as told before, but I would recommend learning splice().

Basically splice() can be used for adding and removing elements from an array:

Removing:

var myArray = [1, 2, 3, 4, 5];
var newArr = myArray.splice(1, 2); // starting from index 1 take two elements from `myArray` and put them into `newArr`

Results:

• myArray: [ 1, 4, 5 ],
• newArr: [ 2, 3 ]

Adding:

var myArray = [1, 2, 3, 4, 5];
myArray.splice(1, 0, "test"); // starting from index 1 take zero elements and add "test" to `myArray`

Result:

• myArray: [ 1, "test", 2, 3, 4, 5 ]

Answer 3

Use unshift instead of push

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.unshift("Lemon");

Answer 4

Use array splice method

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.splice(0, 0, "Lemon")
console.log(fruits)

• jersoft: unshift is fine since he is just a beginner.
• jersoft: @RajaprabhuAravindasamy im just saying that it may add to his confusion. unshift was PREDEFINED to do exactly what he is needing.

Answer 5

I soted this out by using the unshift function

var fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.unshift("Lemon");
