REACT CONTEXT API

React Context API is a way to essentially create global variables that can be passed
around in a React app.

Way to create Context API

We use createContext() and pass it an empty object or a default value
eg : const testContext = react.createContext({})

We then create a Provider and a Consumer component and export them so they are
available for consumption by other components in your application.
eg:
export const testProvider = testContext.Provider;
export const testConsumer = testContext.Consumer;
3
REACT HOC

higher-order component is a function that takes a component and returns a new
component.

A higher-order component (HOC) is an advanced technique in React for reusing
component logic.
eg:
const EnhancedComponent = hoc(OriginalComponent);
