Does TypeScript not effectively perform a check on React?

edit

TypeScript can effectively perform type checking on React code as it provides a way to declare and enforce types for props, state, and more. This can help catch errors early on and improve code reliability. Additionally, TypeScript can provide better auto-completion and documentation for React components. However, TypeScript is not a silver bullet and cannot catch all potential errors in React code. It still requires developers to write code correctly and understand underlying concepts.
