Electron compiles desktop applications for Windows, Linux, and Mac. Meteor creates a full stack web application and potentially iOS and Android apps via Cordova.

React implements a browser-independent DOM system for performance and cross-browser compatibility. We took the opportunity to clean up a few rough edges in browser DOM implementations. In React, all DOM properties and attributes (including event handlers) should be camelCased. For example, the HTML attribute tabindex corresponds to the attribute tabIndex in React. The exception is aria-* and data-* attributes, which should be lowercased. So all DOM attributes and children prop are low-level props. High-level props - are custom props.
