Javascript Array - concat method


The concat method is helpful if you wish to append an array to another existing array. Here is a simple example.
Take a look at the following example 

<html>
<body>

<script type="text/javascript">


var us_cars = ["Ford", "GM"];
var foreign_cars =["Toyota", "Honda"];
var all_cars = [];
all_cars = us_cars.concat(foreign_cars);
document.writeln('All cars :' + all_cars + '<br />');

</script>

</body>
</html>

With the concat method, you can not only join two or more arrays, but can also add additional elements at the end of it. See this example 


<html>
<body>

<script type="text/javascript">


var us_cars = ["Ford", "GM"];
var foreign_cars =["Toyota", "Honda"];
var all_cars = [];
var best_Car = "Hyundai";
all_cars = us_cars.concat(foreign_cars,best_Car);
document.writeln('All cars :' + all_cars + '<br />');

</script>

</body>
</html>
