Introduction to React js
React js is a JavaScript Library for building User Interfaces(UI). React is all about developing Single Page Applications. To describe React, it is all about Components.
What is a Component?
Components are like Cardboard boxes, In one box we can place books, another one we can place utensils. Smiliar to Cardboard box, a single component can be used for the entire application and a single component can be used for particular page.
App Component is the main component for a React Application.
Now let's try to understand Components in detail:
User Profile in Facebook
Some components from above example:
- Navbar Component
- Chat Component
- Address Component
- Cover Component
Common Component
1.Navbar Component: Common for every page in the application.
2.Chat Component: Common for both User Feed and Profile Page.
Page Specific Components
1.Address Component:Page Specific to the User Profile Page.
2.Cover Component: Used for User Profile Page.
This is how the components are used in React.
