Longdescription.long	ESLint is an open source pluggable linting utility for JavaScript and JSX that statically analyzes code to find problems. Many issues can be automatically fixed, and it integrates with text editors and CI pipelines.	Mypy is an optional static type checker for Python that combines the benefits of dynamic and static typing. It enables compile-time type checking with no runtime overhead while allowing gradual migration from dynamic to static typing.
