- 🍽️ The Restaurant Kitchen & Order Management -

-

- Welcome to our bustling restaurant kitchen! Watch as order tickets stack up at - the order station, demonstrating how JavaScript manages function calls through - the Call Stack. Each new order (function call) goes to the top of the stack, and - orders are completed in LIFO order (Last In, First Out). -

🎬 Kitchen Operations
-
    -
  • - New Order: Function call (push to stack) -
    • -
  • - Order Processing: Function execution -
    • -
  • - Order Complete: Function return (pop from stack) -
    • -
  • - Rush Hour: Deep call chains -
    • -
  • - Kitchen Reset: Stack cleared -
    • -
  • - Order Colors: Different function types -

-

- 💡 Try it: Use the controls on the right to add new orders - (function calls) and complete them. Notice how orders are processed in LIFO - order - the last order received is the first one completed! You can also switch - between Kitchen and Assembly Line views using the control panel. -
