Flycheck

Flycheck is a tool used by programmers to automatically check their code for errors or issues as they work. It integrates with text editors to analyze code in real-time, highlighting problems such as typos, syntax mistakes, or other mistakes relevant to the programming language. This immediate feedback helps developers correct errors early, improving code quality and reducing debugging time. Think of it as a spell checker for coding that works live while you're writing, making the development process more efficient and accurate.
