This package contains type definitions for prop-types (https://github.com/facebook/prop-types).

The prop-types package is the original runtime type checking library for React props. It is used in JavaScript projects to ensure that components receive props of the correct type. Unlike @types/prop-types, it does not provide TypeScript type definitions.
TypeScript itself provides static type checking for JavaScript. It can be used in place of prop-types for compile-time type checking in TypeScript projects. TypeScript offers a more comprehensive type system and can catch errors at compile time, whereas prop-types checks types at runtime.
io-ts is a TypeScript library that allows you to define runtime types and interfaces in a single place and derive TypeScript interfaces from them. It provides a different approach to type checking compared to @types/prop-types, as it focuses on runtime type checking and validation with the added benefit of generating TypeScript types.
tcomb is a library for type checking and domain modeling in JavaScript. It provides a similar functionality to prop-types but with a broader scope, including the ability to define complex types and structs. It is not specifically designed for React and does not have TypeScript type definitions like @types/prop-types.
