A framework is a software framework that provides pre-written codes and tools to speed up the process of developing a particular application.
Using a framework is not mandatory, but it saves time and is useful for maintaining structure in advanced projects. Small projects can be developed without using a framework.
Frameworks provide speed, increase code reusability, offer ready-made solutions for issues such as security and performance, and provide developers with a regular structure.
