Async Javascript Part I - Javascript event loop, stack & queue

Async Javascript tutorial - In this discussion about asynchronous Javscript we dive into the Javascript runtime to take a closer look at the Javascript event loop, call stack and message queue with some theory and code examples.

Watch Part II of this video series:

[johnkernelle]

"So when the Javascript runtime encounters an asynchronous function (ex. setTimeout()) in the call stack,
it actually returns immediately via an implicit returns and the asynchronous process continues in the Browser API
the callback is then registered in an event table and subsequently added to the message queue
Once the call stack is empty, then the event loop will grab that callback out of the message queue and add it to the call stack to run it"

- THANK YOU VERY MUCH FOR THIS

Primitive types like Var are stored in Stack, not heap. You can see the var in the call stack too. Heap stores reference types and they are called reference types coz they need a reference to be identified (an address) because they are in heap and that's not ordered, unlike the stack.
