## What it is
A small JavaScript library that converts millisecond durations into human-readable strings like '1 day, 3 hours, 2 minutes'. It supports dozens of languages, configurable units, and works in Node and the browser.

## Use cases
- format milliseconds as human-readable duration
- display elapsed time like '3 seconds' or '2 hours, 5 minutes'
- show localized duration strings in multiple languages
- convert a duration to a specific set of units like hours and minutes
- render countdown or timer durations in a UI

## When to choose
- you need human-readable duration text in JavaScript with broad language support
- you want a tiny dependency-free library usable in Node or the browser
- you need fine control over which units appear and decimal precision

## When to avoid
- you can use the built-in Intl.DurationFormat API instead
- you need to parse duration strings back into milliseconds
- you need date arithmetic or calendar-aware time handling rather than plain durations

## Facets
- artifact type: library
- maturity: maintenance
- function: internationalization, date-time
- domain: developer-tools, web-development
- platform: browser, cross-platform
- tags: duration-formatting, human-readable, javascript, npm-package, localization, nodejs
