It's hard if you don't follow logic or have a hard time committing structural elements or concepts i.e. syntax to memory. I'd say in general that if language learning is difficult or not interesting to you than web development would probably be more of a challenge.

I say that because you will be doing a lot of programming/scipting and will need to know several languages. Javascript for sure, some back end language like PHP, and likely some degree of SQL. In my experience I've found it somewhat similar to learning spoken languages.
