    Comment on it

    Scala is a programming language and full form is Scalable language. It first released in 2003.

    Scala is object-oriented and functional language. Many companies that depend on Java switching to Scala to enhance their development productivity, stability and reliablity.

    Scala is executed by the JVM(Java Virtual Machine) that means its compiled into Java Byte code.

    Scala can execute Java Code because we can use all Java classes here.

    There are some differences like here we have nested functions, closures, Type inference, Traits etc.
     It can use anywhere usually enterprise web applications.
    We use mostly 2 frameworks
    1. Lift Go here
    2. Play framework Go Here

    Below is the command to set up the updated Scala in ubuntu

    sudo apt-get remove scala-library scala
    sudo wget www.scala-lang.org/files/archive/scala-2.10.4.deb
    sudo dpkg -i scala-2.10.4.deb
    sudo apt-get update
    sudo apt-get install scala
    wget http://scalasbt.artifactoryonline.com/scalasbt/sbt-native-packages/org/scala-sbt/sbt/0.12.4/sbt.deb
    sudo dpkg -i sbt.deb
    sudo apt-get update
