There is a replace method for String. You can replace ',,' with a ','.

An example:

var str = "0123456789,, 0987654213,, 0987334213,"; 
var newStr = str.replace(/,,/g,','));

The output:

0123456789, 0987654213, 0987334213,

You can do it very simply, like this using regex.

var str = "0123456789,,0987654213,,0987334213,,,,,9874578";
str=str.replace(/,*,/g,',');
console.log(str)

You can use replace() method with regular expression with g flag to replace all instances ',,' with ',':

str.replace(/,,/g, ",");

Here's a simple example

var str = '0123456789,, 0987654213 ,, 0987334213';
str = str.replace(/,,/g, ",");
console.log(str);

This will replace all occurrences of consecutive commas with a single comma:

str.replace(/,+/g, ',');
