It is however the salient features of React that gave it its popularity. React can be used to develop mobile and web apps that have reusable components.

The next part of this react tutorial explains React Props. React JS follows a distinct data flow approach and manipulation. This can be a little difficult to understand the concepts of ReactJs like State and Props. In the React tutorial, we learn about what the React Props are. This is an important concept in ReactJs.
Props are the short form of properties and it is used to pass the data from one to the other component. It is important to understand its various features and how it is used. It is possible to pass the props to the component only from the parent to the child. The props data are immutable which means that these are read-only.
The ReactJs state is yet another crucial concept of ReactJs and this react tutorial. The React State holds the component data. The component returns the data that is contained within the output state. The State of the component can change with time. When this occurs then the components get re-rendered. It is crucial to understand the basics of ReactJs and the differences between the Props and the State in ReactJs.
The state is used to store the data of the components that need to be rendered to the view. The State is usually updated by the event handlers. It is possible to use the state only in the class components.
The ReactJs component is the building block of the application and this is created by making use of ReactJs. It splits the interface of the user into independent parts.
