Heap allocation is required for languages

Memory in a language runtime is typically divided to handle different lifetimes:

1. Static/Code Area: For global variables and compile-time fixed data.

2. Stack Area: For local variables and function execution flow (handles recursion).

3. Heap Area: For unstructured, dynamically allocated memory whose lifetime is controlled directly by the programmer or a garbage collector.

Because dynamic data structures require memory elements to be allocated and deallocated at unpredictable times during execution without respecting a strict function-return order, Heap allocation is strictly required.
