The CLEAN Framework is a five-step blueprint for writing bug-free and maintainable JavaScript code. Developed by ViissGG, this framework aims to minimize bugs and improve the overall quality of code. The steps include maintaining consistency in coding style, breaking down large functions into smaller, focused ones, optimizing code without compromising readability, respecting legacy code while refactoring, and adopting new features to write more efficient code.
