What is REPL in Scala?
REPL in Scala, or Read-Evaluate-Print Loop, is pronounced as ‘ripple.’ It acts as an Interpreter for executing code from the command prompt. This is the reason REPL is called as Scala Command Line Interface (CLI).
The key use of REPL is to develop and test snippets of code for practice purposes. It is useful for Beginner developers to practice low-level programs.
