A framework in web development is a set of pre-written, reusable code that provides a structure for building web applications. It helps simplify the development process by providing a common set of conventions and tools that developers can use to build robust and scalable web applications.
The importance of using a framework lies in the fact that it provides a standardized approach to solving common web development problems and reduces the amount of code a developer needs to write from scratch, saving time and effort.
Additionally, frameworks typically have built-in security features and are regularly updated, helping to ensure that the applications built with them are secure and up-to-date.
