In Programming: What is a framework?
A framework is a library inside-out.
A library may be a bunch of reusable code that you simply can include inside your program. This lets you quickly access useful functionality. Essentially, you use a library to fill holes inside of your program.
On the opposite hand, you set your code inside a framework. It is reusable code that you simply use to structure your whole program. It is like a library that goes on the outside. Essentially, you employ your program to fill holes inside the framework.
Another way of brooding about it is that a framework may be a library combined with a pre-set thanks to organize your code. Its reusable code bundled in a reusable (but often inflexible) architecture.
