Fusion.js vs hammer.js: What are the differences?

# Introduction
This Markdown code provides key differences between Fusion.js and hammer.js. 

1. **Architecture**: Fusion.js is a universal web framework created by Uber that prioritizes performance and developer experience. It combines React, Redux, and other concepts to create a coherent structure for building web applications. In contrast, hammer.js is a library that focuses on touch gestures for mobile web development, providing a simple API for handling touch events.
2. **Purpose**: Fusion.js is designed for building complex web applications with a focus on scalability, code-splitting, and efficient server-side rendering. It aims to provide a complete solution for building high-performance web apps. On the other hand, hammer.js specifically targets touch events on mobile devices, simplifying the implementation of gestures like tap, swipe, pinch, and rotate.
3. **Community Support**: Fusion.js benefits from being developed by Uber, which provides ongoing support, documentation, and improvements to the framework. It has a growing community of developers contributing to its ecosystem. In contrast, hammer.js is maintained by an open-source community with a focus on touch-related features, which may have a smaller user base compared to Fusion.js.
4. **Dependencies**: Fusion.js has dependencies on React, Redux, and other libraries to support its architecture and functionality. As a result, developers using Fusion.js need to manage these dependencies and ensure compatibility with updates. On the other hand, hammer.js has minimal dependencies, making it lightweight and easy to integrate into existing projects without introducing additional complexities.
5. **Compatibility**: Fusion.js is compatible with a wide range of web development tools and technologies, allowing developers to leverage its features in various project setups. It provides flexibility in integrating with different libraries and frameworks. In contrast, hammer.js is primarily focused on touch events and may not offer as much flexibility in terms of compatibility with different web development environments.
6. **Learning Curve**: Fusion.js may have a steeper learning curve for developers unfamiliar with its architecture and concepts like Redux and server-side rendering. It requires a deeper understanding of these technologies to leverage its full potential. On the other hand, hammer.js is relatively easy to learn and integrate for developers looking to add touch gesture support to their web applications without complex setup or configurations.

In Summary, Fusion.js and hammer.js differ in terms of architecture, purpose, community support, dependencies, compatibility, and learning curve.
