Private Variables in JavaScript

Many programming languages have the concept of public and private methods and properties. Private methods and properties are ones that cannot be seen or accessed from outside their containing class or file.

While JavaScript does not officially have access modifiers that let you mark something as public or private there is a way that we can create Private variables and methods. That is the topic for this video.

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 ?

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?

[uchennachukwuba]

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