Frequently Asked Questions
How does the currency formatter work?
It uses the browser's built-in Intl.NumberFormat API with style: "currency". This correctly places the currency symbol, uses the right decimal separator, and groups digits according to the selected locale — no library needed.
What is a locale and why does it matter?
A locale (e.g. en-US, de-DE, ar-SA) tells the formatter which language and regional conventions to use. For example, 1,234.56 USD in en-US becomes 1.234,56 USD in de-DE — same number, different representation.
Can I use the output in my code?
Yes. Copy the Intl format string shown below the result and paste it directly into JavaScript or TypeScript. It is the exact code that produces the formatted output.
