JSON and AJAX together provide web developers incredible opportunities to integrate external data seamlessly into web applications.
AJAX is the perfect solution for creating connections between data and web user interactions. You can upload your web page with reloading the page, providing a seamless experience for your web visitors. AJAX gives you the ability to request and receive data from servers and external files. All of this is done after your web page loads and the content is already visible to the web users. You can also use AJAX to send data to a server.
