I'm happy with AES and I don't want to write my own crypto.
I was asking for a better AES javascript library, because I found a couple of different js AES libraries, but, as you said, I don't know anything about cryptography, and I wanted to know if some are better than others.
You don't need a better AES implementation (well, you probably do, but that's just the start). You need higher level primitives. There a thousand ways to use AES, and most of them are insecure, including your implementation.
