typescript-eslint is a suite of tools that enable ESLint to lint TypeScript code. It offers a parser @typescript-eslint/parser which converts TypeScript code into an ESTree-compatible format understandable by ESLint. Additionally, it provides a collection of ESLint rules, @typescript-eslint/rules, specifically designed to work with TypeScript code and enforce best practices. It bridges the gap between ESLint and TypeScript, enabling seamless linting for robust and maintainable TypeScript projects.
