In this chapter, we are going to use Scala.js to build the user interface. In this interface, you can select a product to add to your cart, update the number of products that you wish to buy, and remove them from the cart if needed.
Scala.js is a project initiated by Sebastien Doeraene back in 2013. This project is mature and provides a clean way to build frontend applications. Indeed, you can code with a strongly-typed system to avoid stupid mistakes, but this is not only for strong typing; the code—written in Scala—is compiled into a highly efficient JavaScript. It can interoperate with all of the JavaScript frameworks. Moreover, the code can be shared between the front-end and the back-end developers. This feature simplifies communication between developers, as they are using the same concepts and classes.
Thanks to its interoperability...
