Description
@iliakan thanks for creating this site; it is really helpful to my learning js.
I'm not able to use Disqus comments at javascript.info and so I'm placing here mostly a question (it might turn out into an issue or perhaps a PR if you decide so which I'm not sure how to handle yet; my apologies). I'm really trying to understand the tutorial and 'playing around' with the code to grasp it. So please let me know how you want me to place future questions of this sort on javascript-tutorial-en.
So here is my question:
In the Drag'n'Drop with mouse events section in the very first and in the very last examples the code includes this one:
... document.body.append(ball); ...
It seems to me that this line is redundant. After all ball is the id to one of the only two div's and so it is already part of the body hence it does not need any further appending. In my editor when I remove the above line i do not observe any difference in drag-n-drop behaviour of the ball. Let me know if I am not understanding anything. Thanks.
