ms.js

Ever find yourself doing math in your head or writing 1000 * 60 * 60 …? Don't want to add obstrusive Number prototype extensions to your reusable / distributable modules and projects?

ms is a tiny utility that you can leverage when your application needs to accept a number of miliseconds as a parameter.

If a number is supplied to ms, it returns it immediately (e.g: If a string that contains the number is supplied, it returns it immediately as a number (e.g: it returns 100 for '100').

However, if you pass a string with a number and a valid unit, hte number of equivalent ms is returned.

js
ms('1d')      // 86400000
ms('10h')     // 36000000
ms('2h')      // 7200000
ms('1m')      // 60000
ms('5ms')     // 5000
ms('100')     // '100'
ms(100)       // 100
