PropTypes is a utility in JavaScript that is used for type-checking the props passed to components in React. It helps validate whether the expected data types of the props match the provided values. By using PropTypes, developers can define the expected prop types for each component, making it easier to catch and detect potential bugs or incorrect data passed to the component. PropTypes provides a range of validators such as string, number, boolean, array, object, function, etc., which can be used to ensure the integrity of data being passed between components.
