Converting number to string or array to string

We can join all elements of an array and create a sting.

Returning a string by adding all elements of an array by toString

Javascript toString object can connect all elements of an array and return as a string. This way we an use toString to display all elements of the array. This object toString uses commas as separators while adding all the elements.

If you want to specify your own delimiter other than commas then you can use array join function

Let us see this example on how to use toString function.

<script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
document.write(scripts.toString());

</script>
The output of the above script is here
PHP,ASP,JavaScript,HTML

toString with number

We can convert number to string by using toString().
<script>
var my_var = 13;
document.write(my_var.toString()); // output is 13 
document.write(my_var.toString(2)); // output is 1101
document.write(my_var.toString(8)); // output is 15
document.write(my_var.toString(16)); // output is d 
</script>
The input parameter is base value to convert number. By default the base value is taken as 10 in first case.
