Akka vs RxJS: What are the differences?

# Introduction
This Markdown code provides the key differences between Akka and RxJS for use on a website.

1. **Concurrency Model**: Akka is actor-based, meaning concurrency is managed through actors that communicate through message passing. RxJS, on the other hand, is based on observables and operates using reactive programming principles.
2. **Programming Language**: Akka is primarily designed for Java and Scala, whereas RxJS is used with JavaScript and TypeScript.
3. **Error Handling**: Akka provides supervision strategies to handle errors within actors, while RxJS relies on error callbacks to manage errors in observables.
4. **State Management**: Akka allows actors to maintain internal state, while RxJS focuses on stream-based data flow without internal state management in observables.
5. **Use Cases**: Akka is commonly used for distributed systems, concurrency and fault tolerance, while RxJS is often implemented for reactive UI programming and asynchronous operations.
6. **Community and Ecosystem**: Akka has a strong community support and an active ecosystem with various tools and libraries, while RxJS has a large community backing and is widely used in front-end development.

In Summary, this Markdown code highlights key differences between Akka and RxJS, including their concurrency model, programming language, error handling, state management, use cases, and community support.
