Few important points about Scala:

Let’s look at few points about scala to understand more closely.

  • It’s a pure object-oriented programming (OOP) language. Every variable is an object, and every “operator” is a method.
  • It is also a functional programming language(FP) where functions can be passed as variables.
  • You can write your code using OOP, FP or both.
  • Scala code runs on JVM. That’s why, you need JDK for writing Scala applications. It also means that you can easily move from java to Scala.
  • You can also use the wealth of Java libraries. The Scala compiler compiles your Scala code into Java Byte Code, which can then be executed by the ‘scala‘ command.
  • Scala is statically typed language which means, that type checking of a variable will be done at compile time(a static check), instead of doing it at run time(a dynamic check) as done in many languages like (e.g. JavaScript, Objective-C, PHP, Python, Ruby etc.). It may help to find trivial bugs at an early stage.
  • File extension of scala source file may be either .scala or .sc.
