Convert seconds to HH-MM-SS with JavaScript?

Question

How can I convert seconds to an HH-MM-SS string using JavaScript?

Answer 1

Chiming in on this old thread -- the OP stated HH:MM:SS, and many of the solutions work, until you realize you need more than 24 hours listed. And maybe you don't want more than a single line of code. Here you go:

d=(s)=>{f=Math.floor;g=(n)=>('00'+n).slice(-2);return f(s/3600)+':'+g(f(s/60)%60)+':'+g(s%60)}

It returns H+:MM:SS. To use it, simply use:

d(91260);     // returns "25:21:00"
d(960);       // returns "0:16:00"

...I tried to get it to use the least amount of code possible, for a nice one-liner approach.
