This lecture explains the concept of setTimeout in JavaScript, highlighting its asynchronous nature and how it allows code execution to be delayed. The instructor demonstrates the use of setTimeout with examples, explaining the JavaScript runtime environment, including the call stack, memory heap, and event loop. The lecture emphasizes the non-blocking nature of asynchronous code and how the event loop manages execution. The session concludes with an advanced example to solidify understanding.

What is the role of the memory heap in JavaScript's execution context?

What is the significance of the callback queue in JavaScript's execution model?

What are the implications of using setTimeout with a callback function?

How does the event loop work in relation to setTimeout?

How can setTimeout be used to simulate delays in code execution?

Discuss the potential delays that can occur when using setTimeout.
