There is such a small structure. I'm trying to li add a child div, but it doesn't work. If you replace dot.appendChi .. with any other, for example document.body, everything works. What could be the problem?

    @Sergey, forcing someone to try to figure out your problems from the screenshot is not a good idea. The text can be copied and executed, and no one will rewrite the code from the screenshot. - ya.ymer Nov.

Okay. What do you think is happening in the line where innerHTML is assigned?

 dot.innerHTML = i + 1;

Anything that was inside the dot at this point will be destroyed.
