Video: React's Most Useful Types

React.FC, or React.FunctionComponent, is a TypeScript utility type used to define functional components. It ensures the component returns JSX and supports props and default props.

React.elementRef is utilized to obtain the correct ref type for a given component, especially useful when dealing with third-party components where the ref type isn't explicitly known.

The versioning of React and Types React is closely synced. For example, if React is at version 17, Types React will also be at version 17, and this alignment extends to major releases and patch changes.

React does not include its own types by default to allow users the flexibility to install them separately via Types React, ensuring that users can opt for different type versions or setups.

React.ElementType is useful for defining props for components that can accept various types of inputs, including native tags like 'input' or 'div', and ensuring that components are compatible with expected prop types.

React.jsx.element is used for JSX elements specifically, while React.ReactNode includes all possible types that can be rendered by a React component, such as strings, numbers, and JSX elements.

React.jsx.intrinsic elements provide a record of all possible DOM elements with their expected props, allowing developers to easily access and extend these types when creating or manipulating elements in JSX.

React.componentType is a TypeScript utility type that can represent either a class component or a function component in React, allowing for more flexibility in assigning component types.
