    A simple regular expression of ,{2,} will match any instance of 2 more more commas in a row. All matches of that can be replaced with a single comma.

    const str = '1500,,,4000,5000,,6000,,,,,,,,,,,,,,,7000';
const pattern = /,{2,}/g; //finds 2 or more commas in a row
const result = str.replace(pattern, ','); //replaces all matches with a singl comma

console.log(result);
