* Update Lifting State Up not to mix up DOM value with component state
A few weeks ago when teaching my friend, she got stuck on
`this.state.value` vs. `event.target.value`. As the documentation
talked a lot about "values", and the term value could mean three
different things (values in general, the "value" prop / DOM value of
the <input> component and the value in state/props), it was not weird
that she got a bit confused.
* Rename Lifting State Up onChange props to onTemperatureChange
This is in-line with how the temperature is provided as a prop named `temperature`
* Fix one value prop not being renamed to temperature
* Update codepen examples in Lifting state up documentation
* Update devtools state change to reflect docs change
* Improved for a better understanding
that code shouldn't name this parameter onchange. It is so confusing for a starter of ReactJs like me. It looks like that the onChange is an common event from props.
* Update the lifting state up paragraph
I tried to write something to explain to starter programmers in react, how we lift the state up calling a method defined by the ancestor and called by the children that will affect the children element.
* Rewrite Lifting State Up
* Add note about refs on stateless components
* Move info about refs in the stateless components to the main section
* Simplification of the part about refs and functional components
* Tweaks
* Move sections around
* Oops
* Rearrange more sections
* Add onToggle event to details tag
Fixes#8761
* Map onToggle event on ReactDOMFiberComponent
* Tweak doc
* Trap events on setInitialProperties for details tag
* Explain arbitrariness of ref name in callback
The sample code was confusing because it's not clear that "textInput" in this.textInput is an arbitrary name for the ref.
* Tweak wording
* Add benchmarking tutorial
I've written what I hope is the simplest introduction to benchmarking React components. It's meant to be straightforward and easy to follow for beginners. If you agree that it would be helpful, I'd like to add it to the docs.
Would also welcome any and all feedback.
* Just put links together
* Reminder: strip quotes from attributes with JS code
Web developers who are used to standards-compliant HTML and XML will, out of habit, put quotes around all attributes because the standards require them. Other templating systems like ASP.NET also require (or at least allow) quotes around attributes that contain code. This behavior will get users into trouble in JSX because a quoted attribute is always treated as a string literal, even if it contains curly-braced javascript code. Let's add to the docs to help newbies evade this problem.
* Tweak wording
* use an easier word
The word `mandatory` is relatively difficult for people with ESL (English as a second language), so I propose an alternative word.
This would be much easier to understand.
* use simpler word
* Update refs-and-the-dom.md
I want to propose some changes to the Refs and the DOM documentation page.
- Make it clear that string refs are legacy. It seems that this information got lost during the transition to new docs and only some part stayed the same, which was confusing when first reading the docs.
- Clarify and explain that during render, if the ref callback is provided, it will get called twice, first with `null` and then with the rendered DOM element. Discussed in https://github.com/facebook/react/issues/4533 and first proposed docs change in PR #8333.
I've also planned on adding an example for passing the refs up the component chain based on something I've needed to solve myself (e.g. you want to connect two dynamic components by line in React, so you need to both use refs and propagate them up the chain), and while it would be great to read up on this in the docs, it may be too specific for this section; I'd be happy to hear any recommendations.
* Adds more specific information about the callback
* Moved the ref callback description to the Caveats section
* Fixed suggested nits
* Replace 'each render pass' with 'updates'
* Tweak the wording
* Component Lifecycle In Depth documentation
* first steps to improve react component reference
* improved react component reference
- remove the component-lifecycle-in-depth
* add a note for usage of ReactDOM.findDOMNode
* one note on componentWillReceiveProps
* remove old useless images for lifecycle docs
* Tweak wording
