+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.
