What is the purpose of module initialization order in ES modules?
Module initialization order serves to ensure dependencies are properly loaded: 1) Modules are initialized in depth-first post-order traversal of the dependency graph, 2) This ensures that all dependencies are fully initialized before dependent modules, 3) Circular dependencies are handled by partial initialization when needed, 4) The order is deterministic and based on the static module structure, 5) This helps prevent accessing uninitialized exports from dependencies, 6) It's crucial for reliable module initialization in complex applications, 7) Understanding this order is important for managing module side effects and initialization.
