What are some examples of asynchronous requests in programming?

What are some examples of asynchronous requests in programming?

Asynchronous requests allow a program to continue executing while waiting for a response. Examples include AJAX calls in web development, using Promises in JavaScript, and async/await syntax.

Can you explain how AJAX works?

AJAX stands for Asynchronous JavaScript and XML. It allows web pages to update asynchronously by exchanging data with a server in the background, without reloading the entire page.

What is the difference between synchronous and asynchronous requests?

Synchronous requests block the execution of code until a response is received, while asynchronous requests allow the code to run without waiting for the response.

Can you give me a code example of an async request?

Sure! Here's a simple example using fetch in JavaScript:

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data));
