* Migrate conditional tests to gate pragma
I searched through the codebase for this pattern:
```js
describe('test suite', () => {
if (!__EXPERIMENTAL__) { // or some other condition
test("empty test so Jest doesn't complain", () => {});
return;
}
// Unless we're in experimental mode, none of the tests in this block
// will run.
})
```
and converted them to the `@gate` pragma instead.
The reason this pattern isn't preferred is because you end up disabling
more tests than you need to.
* Add flag for www release channels
Using a heuristic where I check a flag that is known to only be enabled
in www. I left a TODO to instead set the release channel explicitly in
each test config.
react
React is a JavaScript library for creating user interfaces.
The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.
Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.
Example Usage
var React = require('react');
