Which loop is faster, while or for?

Question

You can get the same output with for and while loops:

While:

$i = 0;
while ($i <= 10){
  print $i.\"\\n\";
  $i++;
};
         


        

Answer 1

I find the fastest loop is a reverse while loop, e.g:

var i = myArray.length;
while(i--){
  // Do something
}
