What is the concurrency model in JavaScript?
An example of an AI chatbot conversation about JavaScript's concurrency model.
What is the concurrency model in JavaScript?
JavaScript uses an event-driven, non-blocking I/O model, which allows it to handle multiple operations concurrently.
How does the event loop work in this model?
The event loop continuously checks the call stack and the message queue, executing tasks from the queue when the stack is empty.
Can you explain the difference between synchronous and asynchronous code?
Synchronous code runs sequentially, blocking further execution until it completes, while asynchronous code allows other operations to run while waiting.
What are Promises and how do they fit into this model?
Promises are objects that represent the eventual completion (or failure) of an asynchronous operation, allowing for cleaner code management.
