What information is loaded into the heap memory area during program execution?

In the Go language, the heap memory area is used for dynamic memory allocation during program execution. Objects with a long lifespan that cannot be placed on the stack, such as structures, slices, maps, and other data created using the new operator or during variable initialization whose scope extends beyond the current function, are loaded into the heap.

The heap is managed by a garbage collector, which frees memory when objects become inaccessible. Unlike the stack, the heap does not have a strict LIFO structure and can contain objects of arbitrary size and lifespan.
