Wouldn't it be nice to have a syntax sugar like: getInitialState () => {items: [{body: 'sour cream'}]} ❓

@hemanth: you may be interested in https://github.com/reactjs/react-future where we brainstorm some similar apis

👍

I'm unfamiliar with some of the syntax used. such as { } = React. and function definitions without "function". Is this official javascript syntax? If so, where can I read up on that?

combine program language and markup language, like javascript syntactic sugar

@mschipperheyn It's ES6 (ECMA script 6) and it's awesome. Go check it out.
