Question 1

What is the JavaScript Event Loop?

Answer 1

if the stack is empty, the event loop takes the first thing from the queue and pushes it on to the stack which effectively runs it

Question 2

What is different between “blocking” and “non-blocking” with respect to how code is executed?

Answer 2

blocking is when render queue is blocked from being able to execute due to slow code (which clogs up the cal stack or callback queue). non-blocking code allows moments for the render queue to execute.
