Rails is definitely a framework where it requires some knowledge of the framework to really be effective. The adherence to convention over configuration means that a whole lot of things are pretty opaque, and if you don't know the conventions it can seem impossible to know how something is happening (logging is a great example). Javascript is the opposite extreme - nothing is assumed and everything is explicit, so there's a clear and obvious spot (at least in well architected programs) where something is configured. When you know the framework well, however, I find one of Rails' strengths is that it massively decreases the time it takes to get familiar with a codebase. There's never a question of how a developer has organized their code, or configured logging (to take your example), because it's not a choice that Rails gives you - every project is going to work the same.
