When working on a project, maintaining code quality and consistency is just as important as writing functional code. And who has never encountered a piece of code that's hard to understand? Nowadays, refactoring has become a common practice due to code being written without proper patterns and best programming practices. This is where ESLint comes in, helping developers prevent bugs, enforce best practices, and improve maintainability. What is ESLint? ESLint is a powerful linter for JavaScript and TypeScript that analyzes your code, detects issues before they cause problems, and even highlights areas that can be improved to meet the best standards. It enforces rules based on predefined or custom configurations, helping teams maintain a clean and consistent codebase. Why Use ESLint? ✅ Catches errors early Detects common mistakes such as unused variables, incorrect imports, and potential runtime errors before they break your application. ✅ Enforces best practices Encourages good coding habits by following recommended standards, such as using === instead of == this exemple is simple but give us a glimpse the intent of ESlint. ✅ Improves readability and maintainability A well-structured and consistent codebase makes it easier for developers to collaborate and understand the code. It also saves time in the future when adding new features or onboarding new developers. ✅ Boosts development speed By automating code analysis, developers spend less time debugging and more time building features. ✅ Compatible with Prettier ESLint can work alongside Prettier to format and lint your code, ensuring both style and quality are maintained.
