Hi I am following this tutorial. I have the Quiz component. Iam getting warning: "fail propType:Required prop 'books' was not specified in Quiz". And the books are not listed. However if i remove the 'map' function I can list one book :

Instead of styling the Li component via inline style, I want to do it via styled-component. How can I check the state and then assign the color red if the current Li is the selected language?

I have been implementing Tyler McGinnis curriculum to learn react.

It's a weather app. And i'm having trouble debugging a strange behaviour. I'm pretty sure it's something silly that i'm doing or i might have missed an information piece of information.

I am trying to get create-react-app to work. Originally I had a React app working but decided to make it ES6+ syntax over ES5, which exploded on me. After several hours of debugging I decided to start over and deleted everything.

I am working on a server, not locally (if that makes a difference.) The first time I set up React I followed https://tylermcginnis.com/react-js-tutorial-1-5-utilizing-webpack-and-babel-to-build-a-react-js-app/ and got something working but when I stumbled on https://egghead.io/lessons/react-react-fundamentals-development-environment-setup and decided to try create-react-app

I followed the instructions (ran npm create-react-app i -g then create-react-app my-app. When I cd’d in, I found only a barebones package.json file… I thought I was supposed to get essentially a starter structure no config needed... but it only creates the folder and the package.json file. I have been googling hard but cannot seem to find someone with a similar problem. Any help would be GREATLY appreciated.

Unless I misunderstood, the point of create-react-app was to avoid having to tinker with webpack.config.json, babel.rc, or setting up from scratch the package.json. Am I missing something?
