Format a number as currency

Javascript

Intl handles the symbol, the separators and the decimal places for the locale, so you never hand-roll them.

const gbp = new Intl.NumberFormat('en-GB', {
  style: 'currency',
  currency: 'GBP',
});

gbp.format(1234.5);   // '£1,234.50'

Deep clone a value JavaScript structuredClone handles Dates, Maps, Sets and cycles, which JSON round-tripping quietly destroys. Retry a fetch with exponential backoff JavaScript Backs off on each failure and adds jitter, so a recovering service is not hit by every client at the same moment. Debounce without pulling in a library JavaScript Twelve lines covering the case most projects add a dependency for, including cancelling a call that has not fired yet. Copy text to the clipboard JavaScript The modern API needs a secure context and a real user gesture, so the failure path matters as much as the success one. Throttle with a trailing call JavaScript Runs at most once per interval but still fires once more after the last event, so the final state is never dropped. Relative time without a date library JavaScript Turns a timestamp into 'three days ago' using the built-in formatter. Run promises with a concurrency limit JavaScript Keeps a fixed number of jobs in flight rather than firing a thousand requests at once. Fetch with a timeout JavaScript fetch has no timeout of its own. AbortSignal.timeout is the short way to give it one.
