Hello Dev's, I spoke about the React JS Context API Part 2.

The Context API in React.js is a way to share data between components in a tree-like structure without having to pass props manually at every level. It provides a way to pass data through the component tree without having to pass props down manually at every level.

This is especially useful for passing global data or theme information to deeply nested components without explicitly passing them through every level of the component tree.

The main components of the Context API are:


React.createContext:

This function creates a new context object. It accepts a default value, which is used when a component does not find a matching Provider above it in the tree.

Context.Provider: This component is used to provide the context value to the components below it in the tree. It accepts a value prop, which is the data that will be shared with the components.


Context.Consumer or useContext hook: These are used to consume the context value. Context.Consumer is used in class components, while the useContext hook is used in functional components. They allow components to access the context value that was provided by the nearest Context.Provider in the component tree.
