Why are frameworks necessary in modern web development?

Frameworks are essential in web development because as websites become more complex, code bases grow significantly larger and harder to manage properly. While HTML, CSS, and JavaScript provide the foundation, they alone aren't sufficient for efficiently building complex websites. Frameworks like React solve this problem by providing structured approaches to organize and manage large codebases. They help developers create complex websites more efficiently by providing architecture and reusable components. For beginners and professionals alike, learning frameworks like React is crucial as they're widely appreciated by companies and considered essential in today's front-end development landscape.
