Memory Management & Garbage Collection

Primitive values in JavaScript have specific storage behavior: 1) Primitive values (numbers, strings, booleans, etc.) declared as local variables are typically stored on the stack, 2) When primitives are properties of objects, they're stored in the heap with their containing objects, 3) The stack provides faster access for local variable primitives, 4) This hybrid approach optimizes memory usage and access speed, 5) JavaScript engines may apply additional optimizations that can move data between stack and heap, 6) Stack memory is automatically reclaimed when functions return, 7) String primitives may have special handling due to their variable length and potential for optimization through string interning, 8) Modern JavaScript engines might use different strategies depending on the usage pattern detected.
