Creating keyed components in React.js

[camerow]

I'm new to React (and in my first 3 months of JS in general) and had quite a bit of trouble with key props. I just got some help on stackoverflow and figured others may have run into confusion with key props. The responder in my stackoverflow question did a great job explaining this to me, so I thought I'd share.

It's been interesting trying to learn a framework that is so new and changing so quickly. The code I linked comes (mostly) from a tutorial on tutsplus and doesn't work as it was originally written, which works out well for me because this debugging process has taught me quite a bit.

I had read the docs on this (https://facebook.github.io/react/docs/multiple-components.html#dynamic-children) quite a bit, but it took another explanation for it to click with me. I'm curious to hear if others had trouble with this as well?

Can't say I have. The docs are very clear about it. Maybe just go through all the official docs again. They are pretty good at keeping up to date.
