As web technology continues to evolve, so are the resources and techniques used website development. One such method is AJAX. Though it is not a programming language or a proprietary tool, AJAX is an intuitive method that has simplified and enhanced how professional web designers build dynamic web applications. But before we dissect its benefits and the full range of problems it solves, let’s try to understand what it’s all about.
What Is AJAX, and What Does it Stand For?
Why is AJAX Important and Why is It Used?
Benefits of Using AJAX in Web Applications
- AJAX is used to perform callbacks which help minimizes network utilization and enhances efficient operations. By using callbacks, servers will not be required to process loads of data, and this reduces network workload thereby improving performance. This can also be helpful to sites and location that operate on restricted bandwidth.
- It allows clients to make asynchronous calls. By allowing asynchronous calls, AJAX saves time for the client browser by enabling it to display parts of information on a specific page instead of waiting for all data to arrive to allow the users to can act once more.
- Increased performance speed. By allowing sending and retrieval of information to and from the server without the full-page data, AJAX improves the speed, performance, and usability of web applications.
- Increase responsiveness. By eliminating full-page postback, AJAX-enabled applications will be swifter and highly responsive, hence more user-friendly.
New Developments in AJAX
While the commonly used data-type transmission in AJAX was initially XML (hence the XMLHttpRequest), over time this has changed, and other JS-based data-types such as JSON have been introduced. JSON is more preferred today since its objects are much friendlier than XML.
Things to Keep In Mind When Programming With AJAX
The most crucial thing you need to remember is that AJAX is not a packaged product or a proprietary technology. It is just a simplified technique that combines vast programming tools to create robust, interactive, and dynamic web applications. Therefore, if you want to work with AJAX, you need to have:
- Knowledge in HTML
- Some knowledge about the XML or JSON format
- And since AJAX permits you to call server-side language, it is also imperative to know PHP, ASP DOT NET, Java, and Python among others.
