A framework in programming is a structure or set of programming tools that provides a foundation for building software and systems. It includes support programs, compilers, code libraries, toolsets, and APIs to develop software and create systems. A framework is designed to assist in the development process by providing standard, low-level functionality so that developers can focus their efforts on the elements that make the project unique.

Frameworks are typically associated with a specific programming language and can include ready-made components or solutions that are customized 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.

Frameworks are used in software development to assist in the development process, provide standard functionality, and supercharge efficiency by placing the foundation for the project, allowing developers to get started straight away rather than spend weeks laying the initial blocks required to get the code running. Frameworks are a valuable tool for developing applications and can be used in many industries, including web development, data science, and more.
