What is the join method?

Rating:

The join method belongs to the Array object. It is used to convert all the elements in an array to one string, and to place it in a variable. The method separates the elements in an array by a delimiter that is passed as an argument in its parentheses.

The syntax of using the join method is as follows:

arrobj.join("delimiter string")

The following example will demonstrate the use of the join method:

myArray=new Array(1,2,3);
var myVariable=myArray.join(">");
trace(myVariable);
//output: 1>2>3
