Blockly vs. Million.js vs. React vs. python-sql Comparison Chart

The Blockly library adds an editor to your app that represents coding concepts as interlocking blocks. It outputs syntactically correct code in the programming language of your choice. Custom blocks may be created to connect to your own application. Blockly in a browser allows web pages to include a visual code editor for any of Blockly's five supported programming languages, or your own. In Blockly Games, pictured here, users can solve a maze using Blockly's editor on the right. Blockly plugins are self-contained pieces of code that add functionality to Blockly. Plugins can add fields, define themes, create renderers, and much more. Blockly codelabs provide step-by-step instructions on how to use and customize Blockly. Sample projects that show how to use many of Blockly's features.

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.
