How does JavaScript handle asynchronous performance?
An example of an AI chatbot conversation about understanding JavaScript's async performance.
How does JavaScript handle asynchronous performance?
JavaScript uses an event loop and callback functions to manage asynchronous operations, allowing non-blocking execution.
Can you explain the event loop in more detail?
Sure! The event loop continuously checks the call stack and the message queue, executing tasks from the queue when the stack is empty.
What are some common asynchronous patterns in JavaScript?
Common patterns include callbacks, promises, and async/await, each providing different ways to handle asynchronous code.
How do promises improve performance over callbacks?
Promises help avoid callback hell, making code more readable and easier to manage, especially with chaining.
