What browser incompatibilities do jquery allow?

Question

I am currently on a fence about using or not using jquery. I spent several hours exploring the pros and cons of using jquery (or any library, for that matter).

One of the big selling points of jquery is that it frees the developer from worrying about browser incompatibilities. I tried to find any documentation about exactly which incompatibilities it overcomes. I have not found them yet. Can anyone help me with this.

Answer 1

This is a great browser compatibility resource.

this.supportsFixedPosition = (checkDiv.offsetTop === 20 || checkDiv.offsetTop === 15);
