How to use props in React.js? Example Tutorial

If you have ever worked with React, you definitely know what components are. A react application is made of several components and that is why components in React are defined as the building blocks of the application.

Props stand for properties and they are optional. A component works fine without props but they are one of the most useful parts of React.
