Regex to replace character in Javascript

I’m trying to create a regex to replace comma by a dot and only have one dot and delete all of the other ones, for example:

0,23433,222

Should return

0.23433222

Or

123,33

Should return

123.33

>Solution :

Just replace the first comma with a point and then remove all remaining commas. No regular expressions needed:

const str = "0,23433,222";
const res = str.replace(",", ".").replaceAll(",", "");

console.log(res);
