The main problem with React props is that they are not composable. This means that you cannot easily create reusable components by combining different React props values.
React props.children proptype can be one of the following: array: React.PropTypes.array, bool: React.PropTypes.bool, func: React.PropTypes.func, number: React.PropTypes.number, object: React.PropTypes.object, string: React.PropTypes.string, symbol: React.PropTypes.symbol
This line of code is defining the types of data that the React props.children property can hold. The React props.children property is used to pass data from a parent component to a child component.
Proptypes library
Proptypes is a library for creating React components that use prop types. It makes it easy to declare and use prop types in your React components, and it provides a few convenience functions for working with them.
PropTypes makes it easy to declare and use prop types in your React components. You can declare a prop type using the PropTypes function, and then use it in your component’s constructor or state properties.
The PropTypes function also provides a few convenience functions for working with prop types. For example, you can use the isPropType function to check whether a given value is a valid PropType instance.
What is Proptypes for
Proptypes are a feature of React that allow you to declare a type for any component in your app. This type can be used to enforce specific behavior or properties on the component, and it can be used to make sure that your code is correct and consistent.
