Andrew Clark e2fd460cca Bailout in sync task if work is not sync (#20813)
Because we don't cancel synchronous tasks, sometimes more than one
synchronous task ends up being scheduled. This is an artifact of the
fact that we have two different lanes that schedule sync tasks: discrete
and sync. So what can happen is that a discrete update gets scheduled,
then a sync update right after that. Because sync is encoded as higher
priority than discrete, we schedule a second sync task. And since we
don't cancel the first one, there are now two separate sync tasks.

As a next step, what we should do is merge InputDiscreteLane with
SyncLane, then (I believe) this extra bailout wouldn't be necessary,
because there's nothing higher priority than sync that would cause us to
cancel it. Though we may want to add logging to be sure.

react-dom

This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as react to npm.

Installation

npm install react react-dom

Usage

In the browser

var React = require('react');
var ReactDOM = require('react-dom');

class MyComponent extends React.Component {
  render() {
    return <div>Hello World</div>;
  }
}

ReactDOM.render(<MyComponent />, node);

On the server

var React = require('react');
var ReactDOMServer = require('react-dom/server');

class MyComponent extends React.Component {
  render() {
    return <div>Hello World</div>;
  }
}

ReactDOMServer.renderToString(<MyComponent />);
