How does es6 handle memory in classes?

Question

How does memory work in es6? Specifically with their classes and how class members are handled. I am comming from a C # and C++ background(mostly C#). For example if you change a class member value outside a c# class, it acts like a refrence, and the member value recieves that change. This does not apply for c# structs. I am new to the javascript world. T.I.A

Answer 1

There are quite a few differences between classes in C# and Javascript.

For starters, Javascript doesn't really implement classes in the traditional sense as C# and C++.

What appears to be classes in ES6 are just syntactic sugar for what is actually Javascript's prototypal inheritance.

Checkout the following links to get a better understanding of this in Javascript.

Hopefully this will help setup the proper context as you continue researching how Javascript is different from C#.

Answer 2

JavaScript automatic allocates memory when objects are created and frees it when they are not used anymore

We also could release an object from memory by setting it null.
obj = null; //It would be garbage collected.
