Understanding Synchronous vs Asynchronous JavaScript

Most of what you write in JavaScript is Synchronous procedural code read from top to bottom and executed in the single main thread of the JavaScript process.
However, that doesn't mean that JavaScript can't run code in an Asynchronous way.
The video discusses the differences and how that can unexpectedly impact the code that you write.

Hi Steve Griffith. Thanks for this clear explanation. Examples/demo always help understanding things. I always wondered that why sometime javascript works asynchronously and sometimes synchronously. Now it is almost clear. People like you on youtube and other platforms are making our lives easier! Can't thank you enough! :)

I've been searching all around trying to get the answer for an issue I'm having - I'm making a DB call and trying to do something with the result but it keeps returning only after the action has already been taken - and I found all sorts of possible complex solutions that didn't really lead me anywhere. I had already lost hope and you provided me with the solution.
It's simple, straight to the point and very well explained.
Really appreciated! I subscribed for that reason alone!
