Possible disadvantages of Walmart

• Impact on Local Businesses

• Crowded Stores
  Walmart stores can often be crowded, particularly during peak shopping times, which can lead to long wait times and a less enjoyable shopping experience.

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.
