Why the following code prints "0-100"?
(function () {
for ( var i = 100; i >= 0; i -= 5) {
(function() {
var pos = i;
setTimeout(function() {
console.log(" pos = " + pos);
}, (pos + 1)*10);
})();
}
})();
I declare pos = i , which should be in a descending order. This code originated from John Resig' fadeIn() function in his book Pro javascript techniques.
