* "Write Code in Your Editor": Split step 5 into 2 steps
To me it wasn't clear (enough) that I had to copy the file's content from [here](https://codepen.io/gaearon/pen/oWWQNa?editors=0010) *and* add the three lines to the top.
* Update tutorial.md
* Update Portals Documentation
Correct some grammar to be more explicit and clear. Update example CodePen to better match code found in documentation. Update code example styles to match other code examples (ie. 'State and Lifecycle', 'Handling Events').
* Clean up comment to be accurate to example
There was a small comment overlooked when reviewing the documentation. This fixes it to be accurate to the example as well as grammatically correct.
* Update portals.md
* More fixes
* Add ReactTestRenderer documentations
* Add TestRenderer documentations
* TestRenderer is not experiment
* Add a link for jsdom
* Use ES Modules syntax
* Twaek
* Add a Link component
* Use Jest assertions
* Move a documentation for createNodeMock to Idea section
* Renamed
* Tweak
* Rename
* More explicit
* Add a usecase for createNodeMock
Did find and replace in TextMate.
```
find: (?:( \*)( ))?Copyright (?:\(c\) )?(\d{4})\b.+Facebook[\s\S]+(?:this source tree|the same directory)\.$
replace: $1$2Copyright (c) $3-present, Facebook, Inc.\n$1\n$1$2This source code is licensed under the MIT license found in the\n$1$2LICENSE file in the root directory of this source tree.
```
The tutorial hints that a change can be made that allows you to go back
in time then click in the board to create a new entry, but the change is
already present in the example code.
This fix removes the hint and re-words the explanation of the change the
example code is making.
After realizing this was the second time I've visited this exact page within a year and second guessing myself that the `textInput` ref isn't actually the `<input />` element. I decided to attempt to make this a little more explicit; you are actually accessing the method on the child class and not the `focus` method on the dom input element. Having them named the same caused some confusion.
* Improve displayName documentation
* displayName docs: higher-order component lowercased to stay consistent with the rest of the docs
* Rephrase displayName reference docs
* Add AgentConf 2018
We are having another edition of the AgentConf in 2018, which has again a strong focus on react, and we'll be skiing again 😎 Last year's PR for reference: https://github.com/facebook/react/pull/8196
* Update conferences.md
* Adding Crowdin config file to master repo
* Updated to include additional files while ignoring localized community files stored on github
* Additional files ignored
* Included additional files in root docs directory
FB bundles wrap warning() calls in __DEV__
Split dev-mode transforms into separate parts:
1) umd+cjs+fb: Wrap warning calls with process.env checks
2) umd+cjs: Replace error messages with minified codes
Also updated transforms to use __DEV__ since it transforms to smaller code after stripEnvVariables is run.
Also renamed 'scripts/error-codes/dev-expression-with-codes.js' -> 'scripts/error-codes/replace-invariant-error-codes.js'
