My Experience with React: The Hello World
A few things that I noticed were that it's a little hard for a beginner to choose the right material to start learning React because React is more of an ecosystem than a framework where you can choose from different third party components to build the whole framework, so you will have to exactly know what you want. And also in React, they have this component way of thinking which is nothing but breaking the whole app into smaller components and design the application in a top-down approach. One more problem I faced was that a lot of the tutorials were old and the codes were not compatible with newer version of the libraries. In addition to all these, I needed to choose between ES5 and ES6 to write my React app in.
I finally managed to put all the bits together and write a simple and minimal Hello World app in React with Webpack 1.13, Babel 6+ and React 15+. And I used ES5 all the ways since it has better support than ES6 and I am more familiar with it. The code is hosted on my Github account in case you'd like to check it out. Also, if you're looking for a good basic material on React, The React.js Way: Getting Started Tutorial might be useful.
