JavaScript
A programming language primarily used in the frontend of websites to add interactive elements, such as forms, animations, and dynamic content.
What is JavaScript?
JavaScript is the programming language that makes the web interactive. While HTML provides the structure and CSS the styling, JavaScript is responsible for everything that moves, responds, and dynamically changes on a web page. From validating forms to live-updating dashboards and animating transitions, JavaScript makes it all possible. It is the most widely used programming language in the world and forms the basis of virtually every modern web application.
How does JavaScript work?
JavaScript is executed by the browser as soon as a web page loads. It can respond to user actions like clicking, scrolling, and typing, and can dynamically modify page content without reloading. At Wabber, we work with Vue.js and Nuxt, both based on JavaScript, to build fast and responsive user interfaces. With Node.js, JavaScript is also used server-side for real-time features such as live updates in dashboards.
Example
In the TMS that Wabber built for a transport company, JavaScript ensures planners see vehicle positions on a map in real-time. When a driver confirms a delivery, the shipment status is immediately updated in the dashboard without the planner needing to refresh the page. Filters and search functions respond instantly, allowing the planner to quickly find the right information among hundreds of active shipments.
Why is JavaScript important?
The strength of JavaScript lies in its versatility and the enormous ecosystem of libraries and tools. This enables developers to build quickly without compromising on quality. For businesses, this means shorter lead times, lower costs, and software that is easy to extend when business needs change. Moreover, JavaScript makes it possible to use the same language on both the frontend and backend, further increasing efficiency.
Frequently asked questions
What is the difference between JavaScript and TypeScript?
TypeScript is an extension of JavaScript that adds static typing. This means errors are detected earlier in the development process, leading to more reliable code. Wabber uses TypeScript in combination with Vue.js and Nuxt for building robust web applications.
Can JavaScript also be used server-side?
Yes, with Node.js, JavaScript can also run on the server. This makes it possible to build real-time features such as live updates in dashboards and direct communication between systems. At Wabber, we use Node.js for websocket connections and background processes, among other things.
