What is context API in react JS?
The React Context API is a way for a React app to effectively produce global variables that can be passed around. This is the alternative to “prop drilling” or moving props from grandparent to child to parent, and so on. Context is also touted as an easier, lighter approach to state management using Redux.
The constructor is a method used to initialize an object’s state in a class. It automatically called during the creation of an object in a class. The concept of a constructor is the same in React. The constructor in a React component is called before the component is mounted.
How do you create a component of a React function?
We can create a functional component to React by writing a JavaScript function. These functions may or may not receive data as parameters. In the functional Components, the return value is the JSX code to render to the DOM tree. Example: Program to demonstrate the creation of functional components.
What is a class in React?
