Hey your instructor #KOToka

  1. Try-Catch for Sync & Async Errors ๐Ÿ›‘๐Ÿšจ
  • Always use try-catch for synchronous code and async/await functions to avoid unexpected crashes!
  1. Handle Callback Errors๐Ÿ“žโ—
  • In functions like fs.readFile(), make sure to check and handle errors in the callback.
  1. Debugging with Console & Tools ๐Ÿ’ป๐Ÿ”
  • Use console.log() for quick checks, or Chrome DevTools & Node.js Debugger for detailed debugging.
  1. Global Error Handling๐ŸŒ๐Ÿ›ก๏ธ
  • Use process.on('uncaughtException') and process.on('unhandledRejection') to catch errors globally.

Stay error-free and keep your app running smoothly! ๐Ÿ˜„
