I've heard this quite a few times. Are JavaScript loops really faster when counting backward? If so, why? I've seen a few test suite examples showing that reversed loops are quicker, but I can't find any explanation as to why!  I'm...
Just a quick question about the scoping of JavaScript variables.  Why does the alert() function print the value of i instead of returning undefined?  $(document).ready(function () {     for(var i = 0; i < 10; i += 1){     }       alert("What...

var path;  for (var i = 0, c = paths.length; i < c; i++) {     path = paths[i];      fs.lstat(path, function (error, stat)     {         console.log(path); // this outputs always the last element     }); }   How can I access the path variable, tha...

Since i += i is an abbreviation for i = i + i, the following code  for (var i = 0; i<=10; i++) { console.log(i += i) }   should output:  1. 0, because  0 += 0 + 0 (i = 0) 2. 2, because  0 += 1 + 1 (i = 2) 3. 6, because  2 += 2 + 2 (i = 6) 4. 12, b...
