using .join method to convert array to string without commas [duplicate]

Question

Simply like that:

arr.join("")

You can specify an empty string as an argument to join, if no argument is specified a comma is used.

 arr.join('');

The .join() method has a parameter for the separator string. If you want it to be empty instead of the default comma, use

arr.join("");

All you need to do is :

arr.join('');
