5 main Advantages of using JQuery

  What are the advantages of JQuery?

·        Increased Browser Overhead: Sometimes using JQuery and other frameworks, which make nodes selection and DOM manipulation easy, can have adverse effects if you’re not careful and follow some practices for reducing the work the browser has to do.

·        Server load: Server load has major impact on the request processing time. An overloaded server increases the response time and degrades the performance of your application.

·        Poor CPU Utilization: If CPU is not utilized properly it will result in high CPU idle time & low processing team means parallel processing is not being carried out and all processing will be slow.

·        Network delay: The magnitude and variance of network delay between a client and server is also one of the major factors that negatively influence the total response time for serving a set of Web objects from the server to the client.

·        Number of objects and total bytes: The time to retrieve a Web page is dependent on the number and size of objects it contains. Hence focus should be to reduce Bytes and Requests and playing around with load order to make things faster.

I like the way of stack overflow user as they help the users :

function getParameterByName(name)
{
  name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
  var regexS = "[\\?&]" + name + "=([^&#]*)";
  var regex = new RegExp(regexS);
  var results = regex.exec(window.location.search);
  if(results == null)
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}
