// Create an immutable map with three key value pairs
val staff = Map("CEO" -> "Judith Jackson", 
                "CFO" -> "Sally Shields",
                "CTO" -> "Steven Miller")

In [18]:

    
// Test if key exists
staff.contains("CTO")









    Out[18]:





true

// Test is any value exists which contains part of a string
staff.valuesIterator.exists(_.contains("Miller"))
