Syntax of the join() is as given below:
|arrayObject.join( separator )|
This separator is optional and comma(",") is the default separator for the join() method. In this example we have taken an array of three elements and we will be joining them with the separator ("-"). Here is the full code of the example where we are using the join method for joining array elements.
var arr = new Array(3);
document.write("<b>Array before join() is </b>=>"+arr+"<br> ");
document.write("<b>Array after join() is</b>=>"+arr.join("-")+"<br> ");
Example of joining an array with separator "-"
