Today we will learn about Concat() in-built Javascript method.
Javascript Concat() method returns a new array consisted of existing array joined with two or more arrays.
So,it's very easy to concatenate 2 array using Javascript.

We can understand it by an example:-


<body onload="concate_arrays();">

<script type="text/javascript">
function concate_arrays()
var val1 = ["vishal","neeraj","kumar"];
var val2 = [10,20,30];

var text = val1.concat(val2);
alert("Concatnated text is: " + text);

Output will be vishal,neeraj,kumar,10,20,30
