Why TypeScript is a good choice for your ambitious web project

JavaScript is the ideal language for small projects and quick proof-of-concepts. But as the software grows mature, the demand for reliability and maintainability increases. At this stage the last thing you want to be seeing are more "undefined is not a function" errors. TypeScript can help to avoid such errors before they are passed on to your users. And the nice thing about it: Even if your project started without TypeScript, you can still retrofit it in existing JavaScript projects.

A solid foundation for large projects (and for the small ones that dream big)

In a very short time, TypeScript has become the new industry standard on the web. If you have the highest demands of software quality and reliability, there is no avoiding Microsoft's programming language. With TypeScript, clear data models and clean interfaces can be defined in no time at all. A nice - but not to be underestimated - side effect is the increased productivity during refactoring. For this reason, an investment in a TypeScript training course pays for itself after just a few months.

Is this TypeScript workshop right for you?

Our TypeScript workshop is the perfect foundation for ambitious web developers. We support teams coming not just from JavaScript, but other programming languages as well. For the workshop we usually require solid knowledge of JavaScript, but if required we can combine the TypeScript workshop with a JavaScript crash course. At KUKA AG, for example, we were able to support two teams of C# developers in switching to TypeScript.

The benefits of our TypeScript workshop

  • No boring lectures. Instead of spending hours discussing theory, our workshops get straight to the point. 75% of the time is spent coding, we promise!

  • Practical exercises. Abstract exercises are fine, but we prefer to solve the tricky problems that arise in everyday development.

  • Optimal support. We don't abandon workshop participants who may fall behind. From our teaching experience we know how important quick help is when someone gets stuck.

  • We know what we're talking about. We use TypeScript daily in our customer projects. This is how we ensure our workshops address actual issues from working with the language.

  • Customized content. In a preliminary discussion we mix and match the desired workshop topics with the participants.
