Why do you care? As a high level language in a garbage collected environment, it makes no difference to you how they are stored. You can use members of the Marshal class if you require particular memory storage strategies for communication with unmanaged libraries.

The nature of memory allocation is that the allocated block of memory is continguous. Once deallocated, it may never be used again by the application. Back in the day, this could call something known as "heap fragmentation", and would generally crash a program if that program needed to allocate a block of memory had been running long enough to effectively leave no blocks of memory large enough to satisfy the necessary allocation.

.Net's garbage collector is supposed to remedy that problem. Regarding javascript, I don't know the nature of it regarding garbage collecting and heap recovery.

As to .NET, string is a reference class thoroughly mimicking value semantic. It's storage is quite non-trivial, based on the idea of interning.

Please see recent answers on related topic, including mine, here: string is a reference type or value type[^].
