About this Course

AJAX is an important front-end web technology that lets JavaScript communicate with a web server. It lets you load new content without leaving the current page, creating a better, faster experience for your website's visitors. In this course, you'll learn how AJAX works and how you can use JavaScript to communicate with a web server. We'll use plain JavaScript to create AJAX requests and use the response to dynamically update your web pages. Along the way, you'll build mini-projects to reinforce your learning.

What you'll learn

  • AJAX Concepts
  • How to use JavaScript to make AJAX requests
  • Use AJAX callbacks to respond to server responses
  • How to process JSON with JavaScript
