    },
    country: 'india',
};

const result = compare(source, test);
   // Result will be something like:

   {
    regExMatch: 2, // Because it matched 2 regular expressions
    exactMatch: 0, 
    fuzzyMatch: 1, // Because India to india match
    matchCount: 3, // Total keys matched
    mismatchCount: 0,
    unmatchedCount: 0,
    match: true,
    isExactMatch: false, // Because of fuzzyMatch
  }
