* [WIP] Table of attribute behavior * getAttribute helper * add getters for attributes V-Z * More special cases * Add getters for more attributes * Add tagName to attribute config * Switch default accessor to getProperty instead of getAttribute * Add containerTagName and tagName config * Compare result to default value * Add overrideStringValue config option * add section for Sebastian and update a couple more attributes * 'array with string' should use string override, too * Add additional value types Strings on, off, true, false * more attribute updates * More attributes * Remove old directory * add more attribute configs * More attributes * just a couple more attribute updates * More attributes * Fix the seb parts * Fix the seb parts # Conflicts: # scripts/attribute-behavior/src/App.js * More attributes * Prettier * More attributes * More attributes * Fix some bugs in seb's set * Fix the rest of flarnie's section * More attributes * Prettier * Finish my section (Andrew) * Compare against UMD build of master Once we get past MVP stage we can hook this up to the build system so these files are automatically copied over. * Fix attributes that don't have compatible properties Avoid all undefined reads. * Test multiple input types Tests different input types and valueAsNumber property. This value is often NaN. To compare that we also need to switch to Object.is. * Ignore checked in copies of React 15 bundles in attribute fixture **what is the change?:** We checked in bundles of React v15 to run comparisons of attribute behavior on DOM elements between 15 and 16. This commit tells prettier and eslint to ignore those files, and fixes a prettier lint in one other file from that fixture. **why make this change?:** To get CI passing. **test plan:** `yarn prettier` doesn't change anything, eslint passes **issue:** * update README for attribute table fixture * run prettier again
React · 
React is a JavaScript library for building user interfaces.
- Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
- Component-Based: Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.
- Learn Once, Write Anywhere: We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.
Learn how to use React in your own project.
Examples
We have several examples on the website. Here is the first one to get you started:
class HelloMessage extends React.Component {
render() {
return <div>Hello {this.props.name}</div>;
}
}
ReactDOM.render(
<HelloMessage name="John" />,
document.getElementById('container')
);
This example will render "Hello John" into a container on the page.
You'll notice that we used an HTML-like syntax; we call it JSX. JSX is not required to use React, but it makes code more readable, and writing it feels like writing HTML. We recommend using Babel with a React preset to convert JSX into native JavaScript for browsers to digest.
Installation
React is available as the react package on npm. It is also available on a CDN.
React is flexible and can be used in a variety of projects. You can create new apps with it, but you can also gradually introduce it into an existing codebase without doing a rewrite.
The recommended way to install React depends on your project. Here you can find short guides for the most common scenarios:
