Modern JavaScript from the Beginning - Second Edition - Section Introduction-Fetch API and Async / Await

The video tutorial introduces asynchronous JavaScript, focusing on the Fetch API and async/await syntax. It contrasts the older XML HTTP request method with the modern Fetch API for handling data from sources like JSON files and public APIs. The tutorial explains how to perform various HTTP requests using the Fetch API and introduces async/await as a preferred syntax for handling promises, compared to the traditional dot then method. The instructor expresses a preference for async/await and plans to use it more in the course. The video concludes with a preview of the next lesson on the basics of the Fetch API.

What are the two main features discussed in the video for working with asynchronous JavaScript?

• JavaScript and JSON

• GET and POST requests

• Fetch API and async/await

• XML HTTP request and Promises

Which modern method is used to make HTTP requests in JavaScript, as mentioned in the video?

• WebSockets

• Fetch API

• AJAX

• XML HTTP request

What is the Fetch API primarily used for?

• Styling web pages

• Making HTTP requests

• Handling user input

• Managing databases

What is the alternative syntax to .then for handling promises in JavaScript?

• XML HTTP request

• Async/await

• Event listeners

• Callbacks

Why might developers prefer async/await over the .then syntax?
