Create a function that filters out an array of state names into two categories based on the second parameter.

  1. Abbreviations abb
  2. Full names full

Examples

filterStateNames(["Arizona", "CA", "NY", "Nevada"], "abb")
➞ ["CA", "NY"]

filterStateNames(["Arizona", "CA", "NY", "Nevada"], "full")
➞ ["Arizona", "Nevada"]

filterStateNames(["MT", "NJ", "TX", "ID", "IL"], "abb")
➞ ["MT", "NJ", "TX", "ID", "IL"]

filterStateNames(["MT", "NJ", "TX", "ID", "IL"], "full")
➞ []

Notes

State abbreviations will always be in uppercase.
