[Daily Package] ms

ms

ms converts various time formats to milliseconds and vice versa.

/* time format to milliseconds */
ms('2 days')  // 172800000
ms('1d')      // 86400000
ms('10h')     // 36000000
ms('2.5 hrs') // 9000000
ms('2h')      // 7200000
ms('1m')      // 60000

/* milliseconds to time format */
ms(60000)             // "1m"
ms(2 * 60000)         // "2m"
ms(-3 * 60000)        // "-3m"
ms(ms('10 hours'))    // "10h"

Why do we need this?

It's okay to use milliseconds directly in your code.

setTimeout(() => {
  console.log('Hi')
}, 180_000)

But this might not be a good practice, because it's hard to tell how many minutes 180,000 milliseconds is at a glance.

You can improve readability by commenting or using constants.

const THREE_MINUTES_IN_MS = 180_000

setTimeout(() => {
  console.log('Hi')
}, THREE_MINUTES_IN_MS)

I actually used to write in this way, and if you're not handling milliseconds a lot, this is a better option than ms.

However, if you're not, ms is a good choice. You don't have to write an extra variable, and it's much easier to change the time. ?
