Top JavaScript Libraries for Making AJAX Calls

AJAX is a set of web development techniques used by client-side frameworks and libraries to make asynchronous HTTP calls to the server. AJAX stands for Asynchronous JavaScript and XML. AJAX used to be a common name in the web development circles and many of the popular JavaScript widgets were built using AJAX. For instance, a particular user interaction such as a button press would invoke an asynchronous call to the server and the server would retrieve data and return it back to the client—all this without reloading the webpage.
A Modern Reintroduction to AJAX
JavaScript has evolved and, today, we have dynamic websites built using front-end libraries and/or frameworks like React, Angular, Vue, etc. The concept of AJAX has also undergone major changes because modern asynchronous JavaScript calls involve retrieving JSON instead of XML. There are many libraries out there that let you make asynchronous calls to the server from your client-side application. Some of them have made their way into the browser standards, whereas others have a large user-base because they are flexible and easy to use. Some of them support promises whereas others use callbacks. In this article, I’ve covered the top 5 AJAX libraries for fetching data from the server.
