Libraries in programming languages are collections of prewritten code that users can use to optimize tasks.


A framework in programming is a tool that provides ready-made components or solutions that are customized in order to speed up development. A framework may include a library, but is defined by the principle of inversion of control (IoC). With traditional programming, the custom code calls into the library to access reusable code. With IoC, the framework calls on custom pieces of code when necessary.
A framework can include support programs, compilers, code libraries, toolsets, and APIs to develop software and create systems. Open-source frameworks are always being updated and improved.

Framework vs Library

It is very common to confuse the term framework and library, as both are tools used within programming. In fact, as described above in the section “What is a Framework?,” a library is just one tool available within a framework.

A framework is your structure or environment to build your software: it contains access to various tools, including libraries, to assist in your build.

A library is a set of low-level components that can be invoked (called) for a specific outcome. You can access a library directly, called from the code, or a framework can supply access to libraries and call out to the code (inversion of control).
