Why main does not return 0 here?
...return value from a function is normally stored in the eax register of the cpu, so the statement "return 4;" would usually compile to
mov eax, 4;
ret;
and return x (depending on your compiler) would be something like:
mov eax, [ebp + 4];
ret;
if you don't specify a return value then the compil...

...ter implementations use more memory. It's also possible that the number of CPU cores on the tester's computer hurts/helps the concurrent filepath.Walk. Furthermore, filepath.Walk supports recursive decent while os.File.Readdir and ioutil.ReadDir do not.

setImmediate vs. nextTick
...n completes.
So in a case where you're trying to break up a long running, CPU-bound job using recursion, you would now want to use setImmediate rather than process.nextTick to queue the next iteration as otherwise any I/O event callbacks wouldn't get the chance to run between iterations.

Scalar vs. primitive data type - are they the same thing?
