Here are four key ways to handle errors and debug in Node.js:

Hi Guys this is your instructor #KOToka

  1. Try-Catch Blocks 🛑: Wrap code in try-catch blocks to catch and handle synchronous errors.

  2. Event Emitter Error Handling 🔄: Handle errors in asynchronous operations using .on('error') with event emitters.

  3. Use a Debugger 🐛: Use Node.js's built-in debugger or external tools like console.log or node inspect to track bugs.

  4. Centralized Error Handling Middleware ⚙️: In Express.js, use error-handling middleware to manage errors globally.
