Context was missing info on how to update the context after the initial render. Added a simple blurb and an example.
[Docs] 12-context.md code review changes
The code example in `Motivation: Separation of Concerns` now fetches the `Engineering` facebook page instead of the user `pwh`.
With the current version of the graph api, it is impossible to fetch the user picture from an username. However it is still doable for public pages.
* Add a null check to "A Complete Example".
* Fix outdated comment. (Found by @mjomble)
* Replace short dash - with longer dash –.
* Remove backticks from state, because it is not code.
I've seen some people unaware about the fact that you can still specify `.propTypes` and `.defaultProps` when you are defining a functional component by setting them as properties of the function.
I thought clarifying this in the docs could help!
It's mentioned as a note in "JSX in Depth" however I think for clarity and ease of look-up, it would be a good idea to also include it in the JSX Gotchas list?
According to react documentation it is advised to:
NEVER mutate this.state directly, as calling setState() afterwards may replace the mutation you made. Treat this.state as if it were immutable.
https://facebook.github.io/react/docs/animation.html
In this particular case it is probably doesn't matter since setState is called directly after mutation, but it does provide a bad example of state mutation.
Another way of removing an item from an array can be `newItems = this.state.slice(0,i).concat(this.state.slice(i+1))` however the meaning can be less obvious to some.

According to the http://www.2ality.com/2015/11/tc39-process.html it is
not a good idea to guess target ES version until the proposal reaches
later phases.
Even the proposal repository now states
> It is a Stage 2 proposal for ECMAScript. <
