Study Notes
- A JavaScript runtime manages messages using a message queue, which functions as a list of messages to be processed.
- Each message in the queue is associated with a specific function that gets called to handle the message.
- The runtime begins processing messages in the queue by removing the oldest message and invoking its corresponding function.
- The function call creates a new stack frame for its use during processing.
- The event loop continues handling messages in this manner until the stack is empty.
- Once the stack is empty, the event loop moves on to the next message in the queue (if one exists).
