What is JavaScript anyway?

JavaScript is a dynamic, object-oriented programming language used primarily in web development. In combination with HTML and CSS, it is the backbone of any modern website in combination with HTML and CSS. JavaScript is the programming language that allows for a dynamic and flexible user experience. Aside from its power, its most significant advantage is the massive support from third-party framework developers and out-of-the-box readiness - JavaScript can run directly in the browser without any help from third-party development kits (like Java JDK ). In addition to its use in UI design, JavaScript is often found in the back end of websites, native iOS and Android apps, games, and even VR technology.

  • JavaScript Frameworks We Use

    JavaScript is a widely-known and versatile software development tool supported by many third-party frameworks. With our expertise in JavaScript development and in-depth knowledge of these frameworks, we can craft customized solutions that meet the unique demands of your projects. Whether you require interactive user interfaces, real-time updates, or seamless navigation, Perfsol's proficiency in React, Angular, and Vue.js enables us to deliver exceptional results.


    React is the JavaScript development library we use for designing web pages that will handle large amounts of traffic. It allows us to implement the same features without writing separate code. React also bears a declarative nature, simplifying the code, thus making JavaScript development easier to work with.


    Vue.js is a JavaScript development framework known for its lightness, ease of use, and helpful community. It is most often used for the development of user interfaces and single-page applications. However, its most known attribute is directives, which are commands used to manipulate the DOM - the project’s structure, so to speak.


    Angular is a JavaScript development framework written in TypeScript that offers all the capabilities needed to build large-scale projects such as enterprise software. The code of Angular is arranged in modules that allow for the simple organization of code into reusable chunks and make for a quick and efficient development process.


    Next.js is a JavaScript development framework used for server-side rendering of React components. This means that we can render the JavaScript code on our side and send the ready HTML and CSS to the user, making for lighter web pages, even at high amounts of traffic.


    Node is a JavaScript development framework implemented to develop real-time web apps that allow two-sided communication between the server and the client. It is quick, scalable, multi-platform, and easily maintainable.


    Three.js is a unique JavaScript development tool we apply when designing interfaces to create animated 3D computer graphics to display in a web browser. It is surprisingly powerful, allowing for a complex 3D scene with just a couple of lines of JavaScript.

    • What kind of project is JavaScript development best used for?

      JavaScript is mainly used for adding dynamic behavior to web pages. It enhances the user experience by making pages responsive and more attractive. If you have ever used a web page with video players, maps, sliding menus, mouseover elements, or even a login authentication bar - chances are it was built using JavaScript.

    • How much time does JavaScript solution development take?

      Just like with any project - the time required depends on its scale. In fact, the first thing we do when approaching a new JavaScript development task is to evaluate the number of resources it will need. Contact us with the details of your project, and we will estimate the possible timeframes.

    • What platforms support JavaScript?

      Although JavaScript was originally intended to work in a web browser, the plethora of frameworks it can work with allows for cross-platform use of the language. Aside from the web, it is also used in Microsoft Office add-ons, Chrome extensions, Android and iOS apps, VR platforms, or even fitness trackers.

    • Is JavaScript front or back end?

      Short answer: both. In most cases, it is used for the development of the frontend part of websites or apps. However, you cannot deny the ever-growing amount of frameworks and libraries (e.g., Node.js) that make it more and more viable for back-end development using JavaScript.

    • What happens after Perfsol is done with my project?

      We do not like to use the word “done” because even after we finish the initial JavaScript development, we still maintain our solutions with proper care. Should any need for an update or troubleshooting arise - we are ready to help.

    So what are you waiting for?

    We have used JavaScript to create business websites, taxi apps, video streaming services, and much more. And with more than 20 years of collective experience and dozens of satisfied clients under our belt, we are ready for your next challenge. Our company has worked for almost four years now with clients from all over the world, leaving none of them displeased.
