The nice thing about these web frameworks is that it makes rapid prototyping easy, and in doing so, it does things which may seem "magical". I would recommend that one should gain a certain level of understanding of what's going on behind the scenes. In doing so, it won't be as "magical" after all.

The upside of this is you work less & do things faster because there is a lot of functionality pre-built. Solutions become a lot simpler because you are utilising more of the framework, less custom code leaving more time to solve the real problems.

Not to mention, less custom code = less bugs. Although I can only speak for RoR, most of these frameworks have probably done a good share of testing.

That's a great perspective.
