You are assigned to optimize a Node.js application that is experiencing performance bottlenecks. The application heavily relies on reading and writing data to the file system. Which approach would be most effective in optimizing file system-related operations?

  • Use asynchronous file system operations
  • Increase CPU resources
  • Optimize database queries
  • Minimize network requests
In Node.js, using asynchronous file system operations (such as fs.readFile and fs.writeFile) is the most effective way to optimize file system-related operations. This prevents blocking the event loop and ensures that your application remains responsive while reading and writing files.
