## Node
Node is a JavaScript runtime environment which allows JavaScript to run on the server. Node was created in 2019. Node has played a great role for the growth of JavaScript. The React application starts by default at localhost 3000. The create-react-app has configured a node server for the React Application. That is why we need node and node modules. We will see create-react-app soon.

# Components
A React component is small reusable code which is responsible for one part of the application UI. A React application is an aggregation of components. React can help us to build reusable components. The following diagram shows different components. All the components have different border colors. In react we assemble different components together to create an application. We use a JavaScript function or class to make components. If we use a function the component will be a functional component but if we use class the function will be a class based component.

React can do everything that JavaScript can do. React can be used **_to add interactivity to websites, to develop mobile apps, desktop applications, games_**.
I believe you will learn quite a lot in the next 30 days and your programming and problem solving skills will also be improved significantly.
I will use converstational English and less jargons to write this challenge. The content will be continousely updated. If you find a typo or grammar mistakes don't suprised because I don't do any proof read before I publish it. I would recommond you to focus on the main message of the challenge instead of the English and some minor mistakes. I really appreciate if you send me pull requests for improvement and remember to pull first from master before you send pull requests. Most of the images I have used in this challenge came from 30DaysOfJavaScript challenge therefore you may need to rename file names and folders 30DaysOfReact.

Congratulations! You have completed the setup you need to get started with React, but before we dive into React let's do JavaScript refresher. If you are very comfortable with JavaScript you may skip day 1 JavaScript refresher. The JavaScript refresher section is vast and it may take more than one day. From my experience people usually get stuck in React because their JavaScript knowledge is very shallow therefore to fill that gap all the necessary JavaScript feature which can be used in React are covered in the JavaScript refresher section. There are many exercise but you are not required to solve them.
