Getting Started with Scala

Why Scala?

• Expressive
  • First-class functions
  • Closures
• Concise
  • Type inference
  • Literal syntax for function creation
• Java interoperability
  • Can reuse java libraries
  • Can reuse java tools
  • No performance penalty

How Scala?

• Compiles to java bytecode
• Works with any standard JVM
  • Or even some non-standard JVMs like Dalvik
  • Scala compiler written by author of Java compiler

How to install

pip install spylon-kernel
python -m spylon_kernel install

To install scala in Anaconda, first create an empty venv (env-scala in our case) and then install the scala from anaconda-cluster channel.

conda create -n env-scala
conda install -c anaconda-cluster scala
conda install -c conda-forge spylon-kernel
