Question

I’m probably just tired and not thinking clearly, but can someone give a concise way of getting the number of milliseconds passed since the last minute using javascript?

Something like Date.getSeconds(), but that would return milliseconds.

Although I could just do (Date.getSeconds()*1000) + Date.getMilliseconds(), this just seems really awkward and like there has to be a better way.

Thanks!

What about…

Date.now() % 60000

Date.now returns the current UNIX timestamp in ms.

To clarify what’s happening there, the % operator is called modulo and what it does is that it gives you the remainder from dividing the first number by the other one.

An example can be:

20 % 7 === 6
13 % 7 === 6
 6 % 7 === 6

…because…

20 / 7 = 2 + 6 / 7
13 / 7 = 1 + 6 / 7
 6 / 7 = 0 + 6 / 7

(note the remainder 6)
