Advantages of JavaScript for complex web development projects

JavaScript is probably the most versatile language used to extend the functionality of web pages. Here are just a few benefits of JavaScript:

1. Speed and Server Load: JavaScript is executed on the client side. It means, functions run immediately utilizing user’s processing power instead of having to contact the server; thus, increasing page loading speed and saving server’s bandwidth.

2. Versatility: JavaScript is a platform-independent language. It can be used with other languages, in any application or web page regardless of the file extension.

3. User interface interactivity: with JavaScript, you can create interactive interfaces that will respond to the user’s actions without the need of reloading pages and waiting for the server response.

4. Richer interfaces: one of the key advantages of JavaScript is the ability to offer drag-and-drop components and sliders to your site visitors, making interfaces more originative and exciting to the users.

5. Browser Compatibility: JavaScript technology facilitates steady functionality across all modern browsers.

JavaScript Examples in A Real-life Scenario:

Complex Development based on MEAN stack. Using JS, our experts can design a modern and scalable architecture for high load web applications. The best demonstration of our skillset is the food delivery SaaS project, where we used MEAN stack for the development with the JavaScript on both frontend and server-side. As a result, we created a faster web application with the top-notch UI/UX design and advanced functionality.

Backend and API development. You can get a scalable backend powered by Node.js technology, which will be fast, secure, and functional. In a charity portal project, we used Node.js and MongoDB to create a robust backend that included a multi-user system generating statistics and reports for every charity organizations, API for communication with external systems, an automatic bank payment system functionality, and a cashback portal with the donation to organizations.

Visualization effects and Rich interfaces. A JavaScript programmer can create an out-of-the-box visualization functionality and rich interfaces using JavaScript in combination with other modern technologies. For example, we created a house remodeling portal featuring revolutionary 3D modeling functionality, where users can select parameters of the room to repair and start filling in space with desirable furniture items. The user can select colors and materials; and get a 3d visualization of how it will look like in real life.

Increased Interactivity. JavaScript offers incredible dynamic content capabilities and groundbreaking user interactivity features. That is why we applied JavaScript technology to create a quiz platform, where JS generates output messages based on user’s answers.

Input Validation. JavaScript can be used to validate the input before processing it. For example, in our Custom rings e-commerce project, we used JavaScript to develop a validation system for configuration options for all ring types.
