Scala Selected Topics

Scala is the only industrial and pure-functional programming language in the field today. And we think it will remain a key-player in the domain of big data, reactive programming, and software engineering in the coming 20 years. Scala is an application-level programming language that has genuine advantages in big data, micro web services, and software engineering in general. Based on that, we have selected topics that have raised hot-discussions in the last 4 years. Discussions among Scala software engineers in meetups, conferences, and above all, in code review and team-skill-building activities.

All ideas in this book remain subject to discussion by all readers and colleagues, please consider them as opinions that can be argued either contre or in favor.
