Hi,

I have question about adding var bindTask = function(taskListItem, checkBoxEvenHandler){

}

why cannot i add at the bottom of .onclick, why should i add on top of .onclick? var bindTask = function(taskListItem, checkBoxEvenHandler){

}

addButton.onclick = addTask;

for(var i = 0; i < incompleteTasksHolder.children.length; i++){ bindTask(incompleteTasksHolder.children[i], completeTask); }

for(var i = 0; i < completeTasksHolder.children.length; i++){ bindTask(completeTasksHolder.children[i], incomTask); }

If I understand you correctly, it must be added on top of the .onclick function because the variable must be declared prior to it's use.
