What is create-react-context?

The create-react-context package is a polyfill for the React context API for React versions below 16.3. It allows you to create a context object which can be used to pass data through the component tree without having to pass props down manually at every level.

What are create-react-context's main functionalities?

Creating Context

This feature allows you to create a new context object. You can set a default value that can be used when a component does not have a matching Provider above it in the tree.

{"const MyContext = createReactContext(defaultValue);"}

Provider Component

The Provider component is used to set the value of the context to be accessible by all components that are its descendants.

{"<MyContext.Provider value={/* some value */}>{/* some child components */}</MyContext.Provider>"}

Consumer Component

The Consumer component is used to read the current context value, provided by the nearest matching Provider above it in the tree.

{"<MyContext.Consumer>{value => /* render something based on the context value */}</MyContext.Consumer>"}
