What are the advantages of Ajax over WebSockets?
Websocket has no security feature to use. You can send HTML from the WebSocket address to the server using the "setInterval" or "send" options. This means you can control when the request gets done and the response can be as simple as "I got data!". A single "load" event of the client/server allows you to send data of your choice.
Ajax is a great way to load dynamically generated HTML.
everything Ajax does with WebSockets.
Ajax is not exactly "XML/RPC", you must provide XMLHttpRequest calls in your Ajax code if you want to use a web socket connection.
You can use Ajax in combination with CSS3 properties, which adds a bit more complexity. If you have a huge Ajax task you should do it the way CSS3 allows.
Do you know about W3C XML1.0?
By its nature XML is very flexible because all elements of the document are parsed from a large corpus of documents. This means you can create extremely fast applications in relatively few bytes of memory. You can also write very nice and scalable CSS, that can be used on any web page.
What is the XMLHttpRequest object?
The XMLHttpRequest object allows the requesting web server to send files over the wire, so that you can load all the files you wish with their HTML headers. The request is wrapped in an Ajax request object which contains a list of headers, such as content-type, encoding, etc. Once the client receives the requested documents, the request is handled by the server and the entire request is processed by the browser. This is very much like WebSockets. Both WebSockets and XMLHttpRequests are very much the same!
Now let's discuss the benefits of Ajax in web application programming. Ajax technologies helps in interacting with the server-side application without web page refresh and its very useful in development of modern web applications. Here are the benefits of using Ajax:
Support for Asynchronous calls:
The Asynchronous calls are the calls made to the server-side script in background without freezing the browser application. This way you will able to make call to your server-side applications without stopping the user during the call. These way web developers can make interactive web application for your client.
Responsive Application Development:
Fast and responsive web applications:
Web developers should learn Ajax frameworks in the year 2021 and beyond for getting better jobs in the IT industry.
