ms('1m') // 60000
ms('5s') // 5000
ms('100') // 100
`

`js
ms(60000) // "1m"
ms(2 * 60000) // "2m"
ms(ms('10 hours')) // "10h"
`

`js
ms(60000, { long: true }) // "1 minute"
ms(2 * 60000, { long: true }) // "2 minutes"
ms(ms('10 hours'), { long: true }) // "10 hours"
`

- Node/Browser compatible. Published as ms in NPM.
- If a number is supplied to ms, a string with a unit is returned.
- If a string that contains the number is supplied, it returns it as
a number (e.g: it returns 100 for '100'`).
- If you pass a string with a number and a valid unit, the number of
equivalent ms is returned.
