How does asynchronous code work?

Can you explain how asynchronous code works in programming?

Sure! Asynchronous code allows a program to perform tasks without blocking the main thread, enabling it to handle multiple operations simultaneously.

What are some common use cases for asynchronous programming?

Common use cases include handling I/O operations, such as reading files or making network requests, where waiting for a response can slow down the application.

How does it differ from synchronous code?

Synchronous code executes tasks one after another, blocking the execution until each task is completed, while asynchronous code can start a task and move on to others before it finishes.

Can you give me an example of asynchronous code in JavaScript?

Certainly! In JavaScript, you can use the async and await keywords to write asynchronous code that looks synchronous. For example:

async function fetchData() {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    console.log(data);
}
