ESLint
ESLint is a static code analysis tool for identifying problematic patterns and enforcing coding standards in JavaScript and TypeScript code. It helps developers find and fix issues early by analyzing code without executing it, supporting custom rules and integrations with build tools and editors. It is widely used to maintain code quality, consistency, and prevent bugs in modern web development.
Developers should use ESLint to ensure code consistency across teams, catch syntax errors and potential bugs during development, and enforce coding standards like Airbnb or Google style guides. It is essential in collaborative projects to reduce code review time and improve maintainability, especially in large JavaScript/TypeScript applications where manual linting is impractical.
