How to separate number thousands in Javascript?

You can use the toLocaleString() method to comma-separate thousands in a number for a given localization, such as 'en-US'. You can also use the Intl. NumberFormatter object to format a number to a specific localization. Lastly, you can also build your own custom function to get the job done.

function commify(n) {
    var parts = n.toString().split(".");
    const numberPart = parts[0];
    const decimalPart = parts[1];
    const thousands = /\B(?=(\d{3})+(?!\d))/g;
    return numberPart.replace(thousands, ",") + (decimalPart ? "." + decimalPart : "");
}

Output

ommify(9010173.1293) // Returns '9,010,173.1293'
