I want to convert JavaScript Set to string with space.

For example, if I have a set like:

var foo = new Set();

foo.add('hello');

foo.add('world');

foo.add('JavaScript');

And I'd like to print the string from the set: hello world JavaScript (space between each element).

I tried below codes but they are not working:

foo.toString(); // Not working

String(foo); // Not working

Is there simplest and easiest way to convert from Set to string?
