question about memory usage (classes)

[Artem Batogovsky]

In file ClassA takes 180 retained bits on first new, and 80 for all next
ClassB takes 152 retained bits on first new, and 52 for all next

Why it is? For what each bit was taken?

There are some information to read about this?

Thank you for help in understanding =)

p.s. I analyze heap before and after 10 clicks, with heap snapshot

That should elaborate enough for you.

Thank you, but

I read this one, and many other articles, it is not an answer, i still don't understand how each byte of memory is spent.

Okay, may be it is too hard to calculate each bite. But situation that i explain in file was not explained at all.

It will be great if you will say what exactly differ one class from another (ClassA and ClassB).

Short answer: Functions are stateful objects in JavaScript, and each instance of the inner function in ClassA has to remember its own "inc".

Thank you!

There are any way to see real memory consumption? Because i saw with memory profiler in chrome - it is 28 bites diference, it looks like more than one integer variable.
