Why is processing a sorted array faster than processing an unsorted array?
... I'm thinking of situation of array that looks like: [1,2,3,4,5,...998,999,1000, 3, 10001, 10002] ? will this obscure 3 increase running time? Will it be as long as unsorted array?

Algorithm for creating a school timetable
...utation time wise, there was little difference between a small population (100) over a long time and a big population (10k+) over less generations. The computation over the same time produced about the same quality.
The calculation (on some 1GHz CPU) would take some 1h to stabilize near 10^+300, gen...

...hich is the function you're going to use). For example, in g = debounce(f, 100), the value of timeout persists over multiple calls to g. The !timeout check at the end is a mistake I believe, and it is not in the current underscore.js code.

Is JavaScript a pass-by-reference or pass-by-value language?
...t was a proper reference, then everything would have changed. num would be 100, and obj2.item would read "changed".
Instead, the situation is that the item passed in is passed by value. But the item that is passed by value is itself a reference.
Technically, this is called call-by-sharing.
