How can JavaScript improve server responsive time?

By Faruque Ahamed Mollick

A website can be slow and can have slow server response time for many reasons. One of the most common reasons for a website being slow is slow server response time. Visitors then have to wait which is so irritating experience. It creates a bad user experience.

Well, the load on the server can be reduced if you send the load to client side by using some technique. With this way, the load on the server will be reduced because some task will be handled by the client side instead of performing it on the server.

JavaScript is a query language that runs on the client side. It runs on the browser that the user using. If the browser takes the responsibility to perform a task which previously was handled the server side, then obviously a portion of the load will be taken by the browser and thus the load on the server will be reduced.

When the load will be reduced from the server, then the server will respond more quickly then it was responding earlier. This is very clear that it will improve the server response time.

There are many tasks that run on the server side can be run on the client side with the help of JavaScript. Here are some of the examples:

  • Using AJAX functionality of JavaScript, you can improve server response time of a website. AJAX is the abbreviation of Asynchronous JavaScript And XML. Using AJAX, the complete web page will not load. Only some parts of the web page load and communicate with the server. It loads only the required things on the web page and with this way AJAX help to prevent the server from unnecessary load. Thus the server response time will be improved. AJAX will also help you to save the bandwidth of your website.
  • Using JavaScript for form validation instead of validating the form on server side also can reduce the server load time which will improve the server response time. But in case of security, where security matters a lots, you should use server-side validation in these situations.
  • Several times, any kind of error message or warning shown on a web page by analyzing user activity on the server side. But if you use JavaScript to analyze when it is possible to use javaScript instead of doing it on the server side to do this task, then it will help to reduce the load on your server and thus the response time will be improved.
  • There are some tasks like PDF generation, image optimization, online-based calculator and so on that can be performed by JavaScript also. If there is no problem then you should do these tasks by using JavaScript to reduce the load on the server.

From the above content, I hope it is clear to you how JavaScript can reduce the load on the server. I also recommend you use JavaScript when it is possible instead of using the server side language if they do the same functionality and if you want to improve the server response time of your website.
