A Brief Overview of JavaScript

As mentioned, nearly all websites employ HTML, CSS, and JavaScript as its primary building blocks. HTML handles the structure of the website whereas CSS takes care of the designing part. But the site is still static! JavaScript is the soul of the website which breathes life into it.

JavaScript is primarily a frontend web development language that was built as a gap between Java and Scripting Languages. However, it is not related to technical standpoints to the traditional Java Programming language. It is used to make a web page much more interactive and engaging, which results in better user engagement. In fact, without JavaScript, creating an interactive experience for your users can be quite tricky and challenging.

And even though CMS like WordPress and Joomla are making website creation much simpler for people setting up a blog, it still can’t substitute all the amazing things one can achieve with proper JavaScript know-how.

So without further ado, here are some of the Top Advantages of JavaScript in 2020:

Javascript Is Trusted

Your users may not know the first thing about programming or coding, but they know that Javascript is everywhere. All your users have seen the Java logo and used their products at some point. Plus, your users know that Java works well in all situations. You do not need to convince people that your site has been built well when you can show them that you are using Java.

You also must remember that your staff gets a break when they are using Java. This is a very simple system to learn, and it is especially simple for someone who works in coding every day.

Plus, this means that you can participate in the build even if you are only a business manager. You can learn how Javascript works so that you can talk to your staff about the work they are doing. You do not need to be an expert.

While using a website, when you intend on doing some interaction, say clicking on a button, you are sending a request to the server which gets processed, and in return, you get a response. If you link on a link inside an article in Wikipedia, the page will load, and you will be taken to a new Article/Read.

However, you must have also noticed that when you post a status update on Facebook, the entire page doesn’t load again. Or when you are filling up a form, you are sometimes immediately notified of some errors you have typed. All this is possible thanks to JavaScript.

JavaScript code snippets don’t require to be sent to the server side for being processed. This saves the load on the server side. The JavaScript codes in a website get processed using the resources on the user’s system.

Thanks to this server side processing, all the above-mentioned functionalities are possible. Furthermore, it makes the rendering of animations and similar behaviors much less time consuming and a smoother experience.

Now if a callback function is executed which contains the stored information then it will be executed again within the loop.
