Scala is an easy to learn highly scalable language, in which Spark has been written. It has an Interactive Interpreter, REPL (Read-Evaluate-Print-Loop), which allows execution of Scala code by quickly evaluating statements and definitions.

What is Scala REPL?

It’s a kind of a shell in Scala. When you type Scala and press enter, it opens the first shell, wherein you can do some interactive analysis. In Ruby, Python, or any of the SQL languages those REPLs are provided and these are the environments wherein you can just type your programs, test them and if they work fine, then it is a proof of the fact that whatever you have typed is good. Though, REPL comes typically with the languages that can be interpreted.
