In React, how to format a number with commas?

Print a number with commas as thousands separators in JavaScript

You can find a general JS solution for this:

toLocaleString:

// A more complex example: 
number.toLocaleString(); // "1,234,567,890"

// A more complex example: 
var number2 = 1234.56789; // floating point example
number2.toLocaleString(undefined, {maximumFractionDigits:2}) // "1,234.57"

NumberFormat (Safari not supported):

var nf = new Intl.NumberFormat();
nf.format(number); // "1,234,567,890"

var number = 1234567890; // Example number to be converted
