   - question: What is Event Loop in Node.js?
     answer: |
-      The event loop is a single-threaded loop responsible for handling all asynchronous callbacks in Node.js. It continuously checks for events and executes associated callback functions, allowing Node.js to handle asynchronous tasks efficiently. Its non-blocking I/O model ensures that it can process multiple operations simultaneously without waiting for one to complete before moving on to the next, contributing to its scalability and performance.

   - question: What is difference between `fork` and `spawn` methods of `child_process` module?
     answer: |
       The `fork` method is used when you want to run another JavaScript file in a separate worker. It's like having a friend with a specific task. You can communicate with them via messages and they can send messages back to you. The `spawn` method is used when you want to run a command in a separate process. It's like asking someone to do a specific. You can communicate with them via stdin/stdout/stderr, but it's more like giving orders and getting results.

+  - question: How can memory leaks happen in Node.js?
     answer: |
       Memory leaks happen when a program allocates memory but does not release it when it is no longer needed. This can happen due to bugs in the program or due to the way the program is designed. In Node.js, memory leaks can happen due to the use of closures, circular references, and global variables.
