I'm trying to create a regex to replace zeros in list with an empty value but not replace the zeros in ten, twenty, thirty, etc.

list = 0,1,0,20,0,0,1,,1,3,10,30,0

desired list = ,1,,20,,,1,,1,3,10,30,

Using this in the javascript replace function

Any help/tips appreciated!

Should be very simple using word boundaries, \b0\b:

s = s.replace(/\b0\b/g, '');
