I am looking at some code which process an uploaded file and it has
loops like:
for(;;){ // for([two semicolons){
what is the function of the two semicolons? loop until break?
Yeah, same as while (1) {.
AIR for(;;) is slightly more efficient/faster than while(1).
That's silly. Think about it for a moment. How on earth could that
