Regular Expressions in js .replace()

I'm very new to regular expressions and need to strip out some commas. I'm trying to turn Fri,,April,6,,2012 into Fri, April 6, 2012.

Any ideas?
My current code follows. eDate is Fri,,April,6,,2012

eDate = edDate4.replace(/,+/g, ", ").replace(/^,/, "").replace(/,$/, "").split(",");

It returns Fri, April, 6, 2012.

Thanks Juan for your help! When I changed it to

eDate = edDate4.replace(",,", ", ").replace(",,", ", ");

I got Fri, April,6, 2012

Thanks so much.

Here is an example

var stringWithoutComments = s.replace(/(`[^*]*`)|(```[^*]*```)|(''[^*]*'')|(<div [^*]*div>)|(,)|(<[^*]*>)/g, ' ');
console.log(stringWithoutComments);

.replace(/,{2,}/g, ", ").replace(/,(?! )/g, " ")

In your certain example you may do even simpler .replace(/,(?!,)/g, " "), but it will replace ",,," into ",, ", not ", "

Bit of a strange way round it but i would replace all comma's with a space, then anywhere that has two spaces replace with a comma. A bit like so

var edDate4 = "Fri,,April,6,,2012"​;
var eDate = edDate4.replace(/,/g, " ")​​​​​​​​.replace(/\s\s/g, ", ");
alert(eDate) //Gives "Fri, April 6, 2012"
