 How to insert an element into an array in javascript

To create an array in javascript you have to use a variable to store the array data

// first use a variable to  store array value

var Arr;

// This will intialize the array value

// Now create the array obj with the help of new Keyword

Arr = new Array();

// Now add the elements in the Array using the predefined array method

// first to add element we will use the push() method

//Syntax: push()

// Inorder to add elements you will have to follow these steps:

Arr.push();

// Now you can add elements in the array with .push() method

//Just mention the element you want to insert

//for example

Arr.push('apple');

//Now this adds the apple into the array 

// How will the array look like 

//Array[apple] 

//length = 1

// index of apple would be 0

// You can add multiple elements on the go or Add single element one by one as metioned Above

// How to add elements on one Go or in one line

Arr.push('kiwi',grapes','orange');

// This Statement will add multiple element in the ARRAY Arr

//Now Are you wondering what will be the output 

// so don't wait for me try this out in the console

// Output

// Array[apple,kiwi,grapes,orange]

// the element Apple comes from the above line 

// And rest elm were added later

// So the length now incremented to the value 4

// And the index of the elm would be

//Apple:0

//kiwi:1

//grapes:2

//Orange:3

NOTE:: Push() method always add the element  at the end of the array. It returns the array of modified

length.
