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
