javascript - Remove first occurrence of comma in a string

I am looking for a way to remove the first occurrence of a comma in a string, for example

"some text1, some tex2, some text3"

should return instead:

"some text1 some text2, some tex3"

So, the function should only look if there's more than one comma, and if there is, it should remove the first occurrence. This could be probably solved with the regex but I don't know how to write it, any ideas ?

This will do it:

if (str.match(/,.*,/)) { // Check if there are 2 commas
    str = str.replace(',', ''); // Remove the first one
}

When you use the replace method with a string rather than an RE, it just replaces the first match.
