Can someone tell me what exactly the object does not support this property or the method means in IE for JS?

Question

while browsing the internet and through stackoverflow.com I found many posts in forums, etc., where this post occurs in IE, but not in other browsers. the fact is that resolutions vary widely, and I don’t understand what is the best way to avoid this problem.

thanks for the help. Helle
