Help me please

Question

I was doing an animation but it doesn't define .offsetHeight and .getBoundingClientRect for some reason. Here's the code: https://www.sololearn.com/compiler-playground/WLnc1kRf3dt0

p.s. i do it on my computer and i didn't changed the image and fonts when copied it here so don't pay attention to it

Answer 1

There is a conflict between lines 15 and 16.
Since you are using for/of at line 15, variable i will be an HTML element object but line 16 is expecting variable i to be an index(for/in).

I suggest changing variable i to animItem and deleting line 16.

Answer 2

the code is not public....

Answer 3

The sad truth of the matter is that for some reason, sololearn website decided to add an extra layer/ path (compiler-playground) making it so that only members who view via the website can access the link.
