Brian Vaughn 067cc24f55 Profiler actualDuration bugfix (#13313)
* Simplified profiler actualDuration timing

While testing the new DevTools profiler, I noticed that sometimes– in larger, more complicated applications– the actualDuration value was incorrect (either too large, or sometimes negative). I was not able to reproduce this in a smaller application or test (which sucks) but I assume it has something to do with the way I was tracking render times across priorities/roots. So this PR replaces the previous approach with a simpler one.

* Changed bubbling logic after chatting out of band with Andrew

* Replaced __PROFILE__ with feature-flag conditionals in test

* Updated test comment

react

An npm package to get you immediate access to React, without also requiring the JSX transformer. This is especially useful for cases where you want to browserify your module using React.

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.

To use React in production mode, set the environment variable NODE_ENV to production. A minifier that performs dead-code elimination such as UglifyJS is recommended to completely remove the extra code present in development mode.

Example Usage

var React = require('react');
