Very informative and your voice is amazing, thanks for your effort!

normally a variable inside of a function is removed from memory after its parent function is executed, how comes this IIFE function keeps a reference to '_prop1' variable, and how does it know that it needs to keep that reference ?

[@SteveGriffith-Prof3ssorSt3v3]

That's because we are creating a closure. When the inner function makes reference to the variable in the outer function we are protecting it from being destroyed. I have another video about Closures here - kzbin.info/www/bejne/gWrJm4COa6tonKc

Another very cool tutorial !!!

[@uchennachukwuba]

What if a user tries both the obj.prop1 and obj.prop1(Val)? The setter will change the private value

[@SteveGriffith-Prof3ssorSt3v3]

The set method is designed to be the only way that the user can change the private value. It forces the user to go through your function which can do validation of the new value before setting it.

Do private properties and methods in JS classes (#prop, #method) use the same technique behind the scenes? Or they have some other way to hide?

[@SteveGriffith-Prof3ssorSt3v3]

There are different approaches to create private data inside classes, as outlined here by Axel Rauchmayer - exploringjs.com/es6/ch_classes.html#sec_private-data-for-classes This was all before the #private syntax was added. Honestly, I'm not sure whether they used closures or something else behind the scenes. I'm just happy to not have to think about it as much as before. :)
