Node.js features and specs

• Asynchronous and Event-Driven
  Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
• JavaScript Everywhere
  Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
• Large Community and NPM
  Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
• High Performance
  Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
• Scalability
  Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
• JSON Support
  Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages of Node.js

• Callback Hell
  The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
• Not Suitable for CPU-Intensive Tasks
  Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
• Immaturity of Tools
  Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
• Callback and Promise Overheads
  Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
• Fragmented Ecosystem
  The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
• Security Issues
  The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.

Possible disadvantages of Dosh

• Limited Retail Partnerships
  Despite offering cashback at numerous locations, the availability of offers can still be limited, especially for users who do not shop at major retail partners, reducing the potential savings for some users.
• Privacy Concerns
  Some users may be concerned about the privacy and security of linking their credit or debit cards to the app, as it requires access to transaction information.
• Variable Cashback Rates
  Cashback percentages may vary significantly between different retailers and promotions, which can make it difficult for users to predict how much they will save on any given transaction.
• Slow Payouts
  Some users have reported delays in receiving the payout of their earned cashback, which can be frustrating for those expecting to access their earnings promptly.
• Potential Card Limitations
  The app may not support cards from every bank or financial institution, which could prevent some users from taking advantage of the cashback offers.
