A basic regex replace should work:

string.replace(/, /g, ', XXX');

We're searching for all (g flag) commas followed by a space (,) and replacing them with a comma, followed by a space, followed by what you want (, XXX).

This won't replace the first occurrence of test (because the string doesn't start with a comma), so you have to do add your replacement string to the beginning of the result.

'XXX' + string.replace(/, /g, ', XXX');

function replace would do that

var s = "test, test2, test2, test4";
var r = 'XXX'+s.replace(/,\s/g, ', XXX');
