Scalac's blog

Let's talk about one of the most interesting functionalities to test. Namely the manual testing of advertisements in different time zones.

As Zalando kept growing to become an ecommerce giant, at some point they have decided to switch from Java to Scala. Although it’s a major move that required a lot of effort, they managed to do it in less than three months.

What is it about Scala that developers prefer over other languages? Why do we need Scala?

It is inevitable that COVID-19 will disturb not only health but also the economy. Companies need to lock their businesses down and big decisions are being put aside while waiting for better times to come.

When user numbers go up, the performance of applications goes down. And sometimes app owners and business analyzers fail to predict the correct number of users before releasing the product.
