JavaScript Runtime and Message Queue Quiz

• 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).

Test your knowledge about the message queue used in JavaScript runtime, how messages are processed, and the event loop. This quiz covers the handling of messages in the queue, function calls, and stack frames creation.
