What are PropTypes?
PropTypes is a utility library that provides a way to specify the expected data types of props passed to React components. By defining PropTypes for components, developers can catch bugs related to incorrect prop types early during development. PropTypes checks are performed only in development mode, and they help document the expected shape of the data that a component requires.
Syntax:
componentName.propTypes = {
propName : PropTypes.datatype
}
