What does a double * (splat) operator do
...lat can be used on hashes. If opts = {d: 40, e: 50}, then foo 10, opts, f: 60 will assign {f: 60} to c, whereas foo 10, **opts, f: 60 will assign {d: 40, e: 50, f: 60}. To achieve the second effect, previously you would have merged the arrays explicitly.

Why is the standard session lifetime 24 minutes (1440 seconds)?
....
1 day = 24 hours ( hours * 24 = 1 day )
day = 1440 minutes ( minutes * 60 * 24 = 1 day )
day = 86400 seconds ( seconds * 60 * 1440 = 1 day )
Example:
9 days [* 60] = 540 [* 1440] = 777600 seconds
The same is true in reverse:
777600 seconds [/ 1440] = 540 [/ 60] = 9 days

Determining if a number is either a multiple of ten or within a particular set of ranges
...m % 10 == 0) {
// Do something
}
if (num is within 11-20, 31-40, 51-60, 71-80, 91-100) { do this }
The trick here is to look for some sort of commonality among the ranges. Of course, you can always use the "brute force" method:
if ((num > 10 && num <= 20) ||
(num > 30 ...
How to calculate date difference in JavaScript?
