longDescription = ''
|
|
Scala is a general purpose programming language designed to express
|
|
common programming patterns in a concise, elegant, and type-safe way.
|
|
It smoothly integrates features of object-oriented and functional
|
|
languages, enabling Java and other programmers to be more productive.
|
|
Code sizes are typically reduced by a factor of two to three when
|
|
compared to an equivalent Java application.
