Fast loading times with the best user experience. With our JavaScript applications, your web apps work really fast.

What is JavaScript?

JavaScript is the most common implementation of the ECMAScript specification. Developed in 1993, JavaScript, often abbreviated as JS, together with HTML and CSS is one of the basic building blocks of the web. It is often used to add interactivity to web pages or web applications that would otherwise only be able to display static information.


JavaScript frameworks for front and backend

Codana is a specialist in developing high performance JavaScript applications with various frameworks.

We offer our services in project and consultancy mode, with an emphasis on quality and long-term collaboration.

Codana is an expert in React.js and Vue.js, creating high performance frontend experiences, in combination with our PHP web applications. 

As a backend technology we apply Node.js to enable real-time communication. We used this technology in the social media application of the Tomorrowland festival.

Headless, front end and back end

We create headless applications with a JavaScript frontend, but we also use Node.js to realize real-time notifications and chats.

We always put together the best architecture that fits your project.

Web applications for all purposes

We create custom web applications: business applications, product, process and order management, e-commerce, community platforms, intranet platforms and content management. 

We create all kinds of portals and communication applications with our JavaScript and PHP technology.

A full service

We provide a good digital strategy, the best analysis and development and provide hosting and support. Everything under one roof to offer the best service.

You have one point of contact for your entire application, we take care of everything for you.

The benefits of JavaScript apps

JavaScript is the only modern technology for building interactive web applications, and is therefore widely used in our team to deliver applications to the quality standards we want.


As mentioned before, JS is very flexible and can be used for different types of applications. There are different styles of programming that we can stick to, but mostly we stick to already existing standards.


Although JavaScript is known for its frequent new frameworks or libraries, the choices we make are mainly aimed at being mature and stable. This allows us to support applications for a long time. 


Both in terms of user experience and raw performance, JavaScript is incredibly fast today. This makes for a smooth, fun user experience.

How we use JavaScript

In a standard, monolithic, application we use JS mainly to add extra functionality to applications, this varies from adding modal windows, collapsibles or slideshows to more intrusive things like searching on a page, or dynamically loading other parts of the page.

The big advantage of the latter is that we can provide faster initial page loading times, where the most important part of the page is loaded first and where we retrieve the rest of the page later, through an AJAX request, so that the computing power needed to build a complex page can be done in different blocks.

For a decoupled application, where we view the frontend (the visible/usable part of the website) as a separate application, we also use JavaScript. We usually build these with React. The page is built with JavaScript and we then dynamically look at which parts can be retrieved afterwards. This often comes down to a very thorough way of dividing the individual components of the page.

JS is a language that allows different ways of programming, Event-Driven, functional, object-oriented or imperative, its flexibility allows the developer to use their favorite way of programming.

JS is usually used in the end user's browser to add functionality, but since 2009 there is also Node.js. In this capacity JS can also be used to work on the server. Node.js is often used here to manage real-time or asynchronous parts of a website. This fits perfectly into the microservice architecture to make programming languages do what they do best and thus create small pods with discrete functionality.
