Key prop for DOM nodes is actually called 'code'

[rainbow-alex]

I was trying to fix this warning:

Warning: Each child in an array or iterator should have a unique "key" prop. Check the render method of Text. See http://fb.me/react-warning-keys for more information.

After some searching I ended up in react.js, where I found (in ReactElement.createElement):

key = config.code === undefined ? null : '' + config.code;

I finally managed to get rid of the warning by using React.createElement("li", {code: ...}) instead of React.createElement("li", {key: ...}).

This should be fixed, probably in .createElement, or at least in the docs/warning.

That does not make sense, I suspect your copy of React has been modified (probably by search and replace by mistake?).

Yeah, this isn't React – not sure where you got "code". If you search https://fb.me/react-0.13.1.js for "key = config" you'll see that our built copy has key as well.
