PhantomJS vs. React vs. ScrapFly vs. WebKit Comparison Chart

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 and easier to debug. 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. 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 components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props.

WebKit is a fast, open source web browser engine used by Safari, Mail, App Store, and many other applications on macOS, iOS, and Linux. It serves as the foundation for rendering web content and executing JavaScript in these applications. Developers can contribute to the project by reporting bugs or submitting code. Web developers can follow WebKit's development, check feature status, and download Safari Technology Preview to experiment with the latest web technologies. The project emphasizes real-world web compatibility, standards compliance, stability, performance, battery life, security, privacy, portability, usability, and ease of code modification. WebKit is open source and available under the BSD 2-Clause license, with the exception of the WebCore and JavaScriptCore components, which are available under the GNU Lesser General Public License.
