Why hire a JavaScript development company?

They say JavaScript is eating the world. We couldn’t agree more; JavaScript is all over the place, powering application development of platforms such as Facebook, LinkedIn, and Netflix. Since most internet browsers support it, the language is an essential tool in the web developer’s arsenal.

There are many reasons behind JavaScript’s popularity. Its amazing speed, ease of use, and sheer versatility are just the tip of the iceberg.

But what sparked our interest in JavaScript (which developed into a full-blown passion!) was its cross-platform nature that allows delivering interactive and user-friendly products for desktop browsers and mobile devices.

Key benefits of JavaScript.

Incredible speed - Icon

Incredible speed

The language keeps communication with servers to a minimum, boosting application performance like no other language.

Clean code - Icon

Clean code

Since the code is interpreted line by line, errors are indicated together with line number. It takes developers no time to find and correct them.

Universality at frontend - Icon

Universality at frontend

It doesn’t matter whether you use Java, PHP, or Python as your backend technology - you can be sure that JavaScript will provide you with a rich and functional frontend.

Quality at backend - Icon

Quality at backend

One of the most widespread JavaScript frameworks, Node.js, has paved the way towards its application on the backend with some really amazing results.

New data-interchange format - Icon

New data-interchange format

JavaScript Object Notation (JSON) is used to exchange data between a browser and a server, accessible to humans and machines alike - and on its way to becoming an alternative to the Extensible Markup Language (XML).

Mature community - Icon

Mature community

JavaScript is currently the most popular language for web development in the world so you can only imagine how much support and learning developers can get from this rich community.

Our way.

App development based on well-crafted interfaces is at the core of our team. Since the beginning of our company, we have been chasing JavaScript libraries and best practices for delivering fantastic user experience to web and mobile apps.

Our experts went all the way from tools like jQuery, Backbone, and AngularJS to arrive at innovative technologies like React and Vue. Because of that experience, choosing the best tools for projects is built into our application development approach.

Best tools and architecture for solving particular problems - Icon

Best tools and architecture for solving particular problems

We always take your business requirements into account when choosing the architecture for your project. For legacy apps, we recommend progressive enhancement approach. When it comes to new apps, Single Page Application works best for an existing API.

Separation of concerns - Icon

Separation of concerns

No matter what’s the architecture, we strongly believe that separating concerns on each level is key to maintainability. That’s why we carefully separate frontend and backend code on the higher level, and distinguish and modularize visual and logical components on the lower level.

Knowledge sharing and open source - Icon

Knowledge sharing and open source

We like to give back to the community that has offered us so much support in our journey. We present at dedicated meetups, sponsor events, and are now busy bringing some exciting open-source contributions to light.

When developing JavaScript projects, we rely on proven practices but also strive to incorporate the latest trends and technologies. That’s how we bring top business value to our partners.
