AJAX - The reason we can use infinite scroll
#AJAX #coding #programming
In this video, we will learn about the concept, operation principle, and implementation methods of AJAX. AJAX is a technology that updates the screen without refreshing by receiving only the necessary information from the server on the web page.
In the era without AJAX, every user's action resulted in the screen flickering and reloading, which led to user's inconvenience and network traffic waste. However, the advent of AJAX has greatly improved usability by allowing dynamic updates of only necessary parts rather than the entire page.
The implementation methods of AJAX include XMLHTTPRequest and the Fetch API. Both APIs are part of the Web API provided by the web browser, and can be used without installing a separate library. We explain how to call a REST API and manipulate the DOM to dynamically update the web page through actual coding examples.
AJAX is an important technology in web development, contributing greatly to improving user experience and reducing network traffic.
