Call Stack, Callback Queue, and Event Loop

The video tutorial explores the internals of Node.js and the V8 engine to understand asynchronous script execution. It explains the call stack, node APIs, callback queue, and event loop, using examples to illustrate synchronous and asynchronous execution. The tutorial aims to provide a mental model of how Node.js handles asynchronous operations, emphasizing the non-blocking nature of Node.js and the role of the event loop in managing callbacks.

Explain the difference between synchronous and asynchronous function calls.
