Differentiate nil, null, none, and nothing in scala.
Answer / Jasvant Singh
{"Nil": ["Nil is an empty list or empty sequence in Scala. It's a singleton object that extends the abstract class EmptyList."], "Null": ["Null is a reference value representing no object instance in Scala. In other words, it's used when there is no value at all."], "None": ["None is an instance of the Option type, which represents either a value or no value (i.e., absence of a value). It is used in functional programming to handle cases where a function may return no result."], "Nothing": ["Nothing is a subtype of all other types in Scala and represents the unreachable state of a program. It signals that something went wrong during execution."]}
