Prop-types is a library used in React applications to document the intended types of properties passed to components. It helps developers catch bugs early by defining the expected data types for props and validating them during development. Prop-types also serve as a form of self-documentation, making it easier for other developers to understand the component's API.
Compared to TypeScript or Flow, Prop-types is simpler to set up and use, especially for projects that do not require a full type-checking system. It provides a lightweight solution for type checking within React components without the need for additional configuration or tooling.
