This means that it has support for almost all of the functional programming styles that have been developed so far. Another reason for choosing Scala is that it is designed explicitly with object-oriented programmers in mind. Scala positions itself as a mix between object-oriented and functional languages.

In fact, Scala is often used as Java without semicolons, meaning that you can program your Scala programs similarly to how you used to program your Java programs. The preceding reasons facilitate transition for new programmers greatly. Also, Scala...
