Props - Components can either fetch data from an API and store in the local state, or they can ingest data using props, which are like inlets into a prop. React takes care of the underlying browser specific implementation internally.6.

React wraps browser specific implementations into Synthetic Events, which are dispatched on user interaction. Synthetic Events - Browsers handle events differently. Internally, JSX is compiled into efficient render functions. JSX - The render method inside a class component or the function component itself allows you to use JSX, which is like an XML language that incorporates JavaScript expressions. The image below demonstrates a login interface which has been composed together using three components.4. By breaking down UIs into functional and atomic pieces, you can compose together interfaces that scale well. Components - Everything that you build with React, is known as a component. This is known as declarative programming where you simply describe your views in terms of data that it has to show.3.

You simply update the state and React manages the rest of the process that leads to the view getting updated. Declarative Programming & State - State is the data that describes what your component renders as its content.

The Virtual DOM - An in-memory representation of the DOM and a reconciliation algorithm that is at the heart of React’s performance.2. By composing components together, you can create UIs that scale well and deliver performance.What sets React apart is its feature set.1. React allows you to disintegrate a user interface into components, a functional unit of an interface. By Sachin Bhatnagar What is React?React is a library by Facebook that allows you to create super performant user interfaces.
