TL;DR

We plan to implement the Proposal forIntl.DurationFormat in GraalJS.

Details

• Time Duration is how long something lasts, from the start to end. It can be represented by a single time unit or multiple ones.
  • For example,
    • 10000 seconds
    • 2 hours 46 minutes 40 seconds
• Every locale has its own way to format duration.
  • For example:
    • en-US: 1 hour, 46 minutes and 40 seconds
    • fr-FR: 1 heure, 46 minutes et 40 secondes
• There are multiple widths for the time duration.
  • For example, wide and short
    • 1 hour, 46 minutes and 40 seconds → Wide
    • 1 hr, 46 min, 40 sec → Short

newIntl.DurationFormat("fr-FR",{style:"long"}).format({hours:1,minutes:46,seconds:40,});// => "1 heure, 46 minutes et 40 secondes"
