🔍 What You'll Learn:
1. Event Loop Structure and Functionality
2. Phases of the Event Loop Explained
3. Microtasks vs. Macro Tasks
4. Timing and Execution Order
5. I/O and Non-blocking Operations
6. Avoiding Blocking the Event Loop
7. Real-world Code Examples
🔽We will cover interview questions below:
1. Explain the role of the event loop in Node.js. Why is it important for handling asynchronous operations?
2. What are the different phases of the Node.js event loop, and what tasks are handled in each phase?
3. How does the setTimeout function work in Node.js, and why might it not execute exactly after the specified delay?
4. Differentiate between setImmediate and setTimeout. In what scenario would you use each?
5. What is the difference between microtasks and macro tasks in Node.js? Give examples of each.
6. Describe the behavior and priority of process.nextTick() compared to setImmediate().
7. What happens in the Poll phase of the event loop, and why is it considered the 'heart' of the loop?
8. Why is it important to avoid blocking the event loop, and how can you prevent it in a Node.js application?
9. When would you use worker threads or child processes to handle computation instead of relying solely on the event loop?
