Benefits Of Using JavaScript: JavaScript is currently the primary language for building dynamic user interfaces, and it’s becoming increasingly common in other fields, too. It’s one of the most widely-used programming languages in the world, and it’s no wonder that JavaScript is so popular. It does a lot of things really well, not the least of which is the way it allows you to interact with your site on the front end. But even beyond that, there are some real benefits to using JavaScript in development that might not be apparent to people who haven’t looked at it. Let’s dive deep into them.

Faster Website Loading Times
If you’re just starting out, you might be wondering how you can speed up your website or application’s loading times, especially as we now live in the age of mobile and the ever-increasing amount of data being transmitted through a smartphone or other mobile device.
The first thing you need to do is figure out what exactly is slowing down the load time on your site. Often, it’s a matter of optimizing your images. If you’ve got large PNGs, optimize them or split them up into different sizes. But if you’re building a mobile app, try building a custom HTML5 framework to make your apps load faster. Alternatively, you can make it much faster for your users to load by including JavaScript. After all, if your site has a lot of content, the browser needs to go back to the server to retrieve that content. It’s also possible to reduce this by having JavaScript build certain parts of the page.
Interactive and Dynamic Forms
One of the most significant advantages that JavaScript has allowed developers to interact with their users is through forms. With so many different browser types, having one version of a form that works with all of them isn’t a viable option, so you have to build a lot of custom functionality. But with JavaScript, you can eliminate a lot of the work.
Most common web forms can now be accomplished with JavaScript using frameworks, such as jQuery or Prototype. The key is figuring out the best way to interact with the browser and what you want to do with your site, and seeing where JavaScript can improve upon what you’ve already got. Even if you’re only writing a simple form, JavaScript is an excellent tool for extending its interactivity. For example, pre-vetted JavaScript developers can add live validation to forms. Thus, if a field isn’t in a format that the user can input or if the input is too small, it will alert you as the user tries to submit the form.
Better SEO Performance Metrics
Another great benefit of JavaScript is that it makes your site more searchable. With web crawlers like Googlebot, spiders are able to access all of the resources on your site, but as with most sites, not everything is readily available to the search engine. And since JavaScript is used to dynamically create many of your webpages, if you use a framework such as AngularJS, then the resources it creates will be much easier for Google to index.
Better Security
One of the other major benefits of JavaScript is that it can make your site much more secure. For instance, on websites that have JavaScript, developers are often able to inject malicious code into the websites through the use of social engineering, XSS attacks, and cross-site scripting. In some cases, malicious code can lead to your site being hacked or compromised. But if you’re building an app or site that has a lot of sensitive information, then you can use HTML5 to limit what kinds of things the user can access and how they can interact with your site.
For instance, you might want to use JavaScript and HTML5 to limit the access a user can have to a specific page, a specific document, or an entire site. You might want to make sure that a user has to log into the site before they can see the page you want them to view. You might even want to protect a site by making sure that a visitor must perform certain actions to access a page.
Make the Right Decision for Your Web Project
JavaScript technology is now the de-facto web programming language used by most sites, which makes it extremely important for any developer to know. If you are still wondering if JavaScript is your go-to solution, then take your time and re-read all the above benefits that it offers.
