typescript-eslint-parser is deprecated; leverage @typescript-eslint/parser instead. This package was instrumental in enabling ESLint to lint TypeScript codebases. Previously maintained to bridge the gap before official support, it parses TypeScript code into an AST compatible with ESLint. While functional, it's no longer actively supported. Rely on the officially endorsed @typescript-eslint/parser for future TypeScript and ESLint integration for enhanced performance and maintenance. Migration strongly recommended.
