Can we use Scala for commercial purpose? If yes any licencing is required? Any thing to take care of before using it in commercia lproduct?
Scala is licensed under a BSD-3-Clause-license. So you only have to adhere to its rules, you don’t have to specially license it for commercial use. There is no distinction between commercial and non-commercial for using Scala.
(Note that all future Scala releases will be Apache 2 licensed instead. reference: Moving to the Apache v2.0 License - #5 by SethTisue - Announcements - Scala Contributors)
