#essay – Libraries vs. Frameworks –
Libraries are useful collections of code that you can call to do bits of work. In the case of a web app, there are things that are common to pretty much all of them: Receiving HTTP connections, URL routing, database connections, HTML generation or constructing SQL statements from fragments. There are libraries that do all of these for you.
Frameworks aim to solve all your problems for you in one fell swoop. They collect these libraries together in one big package and you generally have very little choice in how your problems are solved.
