-Alternative JSON parse function that uses Recursive Descent instead of eval. -Alternative JSON parse function that uses a State Machine instead of eval. -Contains two functions, JSON.decycle and JSON.retrocycle, which make it possible to encode cyclical structures and dags in JSON, and to then recover them.

Lightweight DOM For Better Performance Easy Learning Curve A desired interface can be created in a relatively easy manner Components Support And Little Dependencies Easy interface design and learning API. Significant performance gains over other JavaScript frameworks. Faster updates. React creates a new virtual DOM and a patching mechanism with the most recent data and efficiently compares it against the previous version, creating a minimal list of update portions to be made to the real DOM to bring it in sync, rather than having to re-render the entire site on each change. Server-side rendering allows creating isomorphic/universal web apps. Easy import of components although having very little dependencies. Good code reuse. Great for JavaScript debugging. It is entirely possible to augment Angular with React to enhance performance of troublesome components. Fully component based architecture. JSX, a JavaScript extension syntax allowing quoting of HTML and using HTML tag syntax to render subcomponents.
