Ajax stands for Asynchronous JavaScript and XML. It is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications. With Ajax, web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behaviour of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows web pages and, by extension, web applications, to change content dynamically without the need to reload the entire page.
Ajax is implemented using a combination of the following technologies:
- JavaScript: JavaScript is a scripting language that is used to add interactivity to web pages. It is also used to send and receive data from the server using the XMLHttpRequest object.
- XMLHttpRequest: The XMLHttpRequest object is a built-in object in all major web browsers that allows JavaScript to send and receive data from a server without reloading the page.
- XML: XML is a markup language that is used to represent data in a structured format. It is often used to exchange data between the client and server in Ajax applications. However, XML is not required for Ajax, and JSON is often used instead because it is more lightweight and easier to parse.
How Ajax Works
When a user interacts with an Ajax web page, JavaScript is used to send a request to the server. The request can be either a GET or POST request, and it can contain data such as the user's input or the current state of the web page.
The server then processes the request and returns a response. The response can be in any format, but it is often XML or JSON.
Once the response is received, JavaScript is used to update the web page without reloading it. This can be done by updating the DOM (Document Object Model), which is a tree representation of the web page.
Benefits of Ajax
Ajax offers a number of benefits over traditional web development techniques, including:
- Improved performance: Ajax applications are more responsive and faster than traditional web applications because they do not need to reload the entire page to update the content.
- Increased user interaction: Ajax allows web applications to be more interactive and engaging for users. For example, Ajax can be used to create real-time chat applications and social networking applications.
- Reduced bandwidth usage: Ajax applications use less bandwidth than traditional web applications because they do not need to send the entire page back to the server every time the content is updated.
Examples of Ajax
Ajax is used in a wide variety of web applications, including:
- Social networking applications: Ajax is used to power the real-time updates and notifications that are seen in social networking applications such as Facebook and Twitter.
- Real-time chat applications: Ajax is used to power the real-time chat functionality in applications such as Google Chat and WhatsApp.
- Online games: Ajax is used to power the real-time multiplayer functionality in online games such as World of Warcraft and League of Legends.
- E-commerce applications: Ajax is used to power the real-time shopping cart updates and product recommendations that are seen in e-commerce applications such as Amazon and eBay.
- Search engines: Ajax is used to power the real-time search results and suggestions that are seen in search engines such as Google and Bing.
Conclusion
Ajax is a powerful set of web development techniques that can be used to create highly interactive and responsive web applications. It is used in a wide variety of web applications, including social networking applications, real-time chat applications, online games, e-commerce applications, and search engines.
Why Use Ajax?
There are a number of reasons why you might want to use Ajax in your web applications. Some of the benefits of Ajax include:
- Improved performance: Ajax applications can be faster and more responsive than traditional web applications because they do not need to reload the entire page to update the content.
- Increased user interaction: Ajax allows web applications to be more interactive and engaging for users. For example, Ajax can be used to create real-time chat applications and social networking applications.
- Reduced bandwidth usage: Ajax applications use less bandwidth than traditional web applications because they do not need to send the entire page back to the server every time the content is updated.
When to Use Ajax
Ajax is a powerful tool, but it is not always the best solution for every problem. Here are a few things to consider when deciding whether or not to use Ajax in your web application:
- Does your application need to be highly responsive? If your application needs to be able to update its content in real time, then Ajax is a good choice.
- Does your application need to be highly interactive? If your application needs to allow users to interact with it in real time, then Ajax is a good choice.
- **Do you need to reduce bandwidth

In this video we take a look at how Twitter uses AJAX to refresh their timeline and spend some time talking about the javascript XMLHttpRequest object. Then we add an AJAX refresh to an application which pulls images from instagram. Finally when we hit a snag due to the browser same-origin policy we explore JSONP as an alternative to XHR.
