 I will use conversational English and less jargons to write this challenge. The content will be continuously updated. If you find a typo or grammar mistakes don't be surprised because I don't do any proof read before I publish it. I would recommend 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.
 If you are good at arrays, loops, functions, objects, functional programming, destructuring and spreading and class then you will be able to follow the challenge properly. Otherwise, I strongly recommend you to check [30DaysOfJavaScript](https://github.com/Asabeneh/30-Days-Of-JavaScript).
