Formatting a float number as a currency string in JavaScript

I have a float number that is based on a calculation logic to get a price for an item. I’d like to display that number as a string like “$ 1,234.56”

@NathanCruzAug 12.2022 — A quick way to do this is by using toFixed() to round the number to a specific number of decimal places and then using regex to add the comma. Have in mind that .toFixed() rounds the number down (0-4) or up (5-9) you can then just concatenate "$ " with the result.
(1234.56123).toFixed(2).replace(/\d(?=(\d{3})+\.)/g, '$&,'); // 1,234.56
