What is Scala?

Scala is an acronym for “Scalable Language”. Thismeans that Scala grows with you. You can playwith it by typing one-line expressions andobserving the results. But you can also rely on itfor large mission critical systems, as manycompanies, including Twitter, LinkedIn, or Inteldo.


Object-functional Programming Language

• Scala is a pure-bred object-oriented language. Conceptually,every value is an object and every operation is a method-call.The language supports advanced component architecturesthrough classes and traits.

• Even though its syntax is fairly conventional, Scala is also afull-blown functional language. It has everything you wouldexpect, including first-class functions, a library with efficientimmutable data structures, and a general preference ofimmutability over mutation.


What is type System?

• “A type system is a tractable syntactic method for proving the absence of certain program behaviors by classifying phrases according to the kinds of values they compute.“ – Benjamin Piercejeudi


What is Type?

• A Type defines a set of values a variable can posses and a set of functions that can be applied to these values.

• In Functional Languages like Scala, a Function is also a Type that can be assigned to a variable.


Internal DSLs in Scala

• Domain-Specific Language” A Domain-Specific Language is a programming language or executable specification language that offers, through appropriate notations and abstractions, expressive power focused on, and usually restricted to, a particular problem domain.

• Examples of DSLs :

• HTML

• Verilog and VHDL hardware description languages

• Mata for matrix programming

• Mathematica and Maxima for symbolic mathematics

• Spreadsheet formulas and macros


Seamless Java Interop

• Scala runs on the JVM. Java and Scala classes can be freely mixed, no matter whether they reside in different projects or in the same. They can even mutually refer to each other, the Scala compiler contains a subset of a Java compiler to make sense of such recursive dependencies.
