Convert seconds to HH:MM:SS format in JavaScript.

convert-seconds.js

new Date(seconds * 1000).toISOString().substr(11, 8)

super!

limitation: the duration cannot be more than 24 hours (it'll overflow)

nice!

Phenomenal dude!

Nice, thanks!

This is incredible, thanks!

great

Why multiply seconds into 1000? can anyone explain?

@shahab570 Because JavaScript Date objects work with milliseconds: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

Failed: secToTime(359999) - Expected: '99:59:59', instead got: '03:59:59'

Overflow. Should only be used with seconds value of less that 24 hours (86400).

awesome one-liner!

Came looking for an answer, and I suppose I found it 😂
