What are some examples of asynchronous code?

Can you explain what asynchronous code is?

Asynchronous code allows tasks to run independently without blocking the main thread, improving efficiency.

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

Sure! Here's a simple example using setTimeout:

console.log('Start');
setTimeout(() => {
  console.log('This runs after 2 seconds');
}, 2000);
console.log('End');

In this code, 'Start' and 'End' will log immediately, while the message inside setTimeout will log after 2 seconds.

What about using async/await?

Absolutely! Here's an example:

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

This code fetches data from an API asynchronously, allowing other code to run while waiting for the response.
