Label outside the scope
Hi, I don't understand this part. Why do we have to return it in the function to work ?
In the video: "with appendToLI, I can't append the checkbox to it. Well that's because the label is being created outside the scope beyond the checkbox's reach. So if appendToLI returned the label once it was finished, you could call appendChild on it and pass in the checkbox."

Normally, any variables created in a function go out of scope and are disposed the moment the function ends. However, any value that is returned by the function is available to the caller.
