Edit Question
Title
Body
I have read a number of explanations about closures and closures inside loops. I have a hard time understanding the concept. I have this code: Is there a way to reduce the code as much as possible so the concept of closure can be made clearer. I am having a hard time understanding the part in which the i is inside two parenthesis. Thanks function addLinks () { for (var i=0, link; i<5; i++) { link = document.createElement("a"); link.innerHTML = "Link " + i; link.onclick = function (num) { return function () { alert(num); }; }(i); document.body.appendChild(link); } } window.onload = addLinks;
