JavaScript: Convert array to string (comma separated)

JavaScript makes it very easy for you, so that you do not have to handle your own loops or functions. The function that you are looking for is called join ():

var NumberArray = [1,2,3,4];
var NumberString = NumberArray.join(', ');
alert(NumberString);
// output: "1, 2, 3, 4"

The function join() simply expects the string to be written between the elements as parameter. The return value of join() is then the final string.

In the example above, we are using ', ' (a comma and a space) as separator, but we can also use any other character, we would like to use as delimiter.
