Why using foreach, map, flatMap etc. are considered better than using get for Scala Options? If I useisEmpty I can call get safely.

Put simply:

  • If you need to do something (a procedure when you don't need to capture the return value of each invocation) only if the option is defined (i.e. is a Some): use foreach (if you care about the results of each invocation, use map)

  • If you need to do something if the option defined and something else if it's not: use isDefined in an if statement

  • If you need the value if the option is a Some, or a default value if it is a None: use getOrElse

Trying to perform our Operations with get is more imperative style where u need to tel what to do and how to do . In other words , we are dictating things and digging more into the Options internals. Where as map,flatmap are more functional way of doing things where we are say what to do but not how to do.
