Creating a Helper Function for Type Matching in TypeScript

    type valueT:   'IsA' | 'IsAReverse' | 'DerivedFrom' | 'DerivedFromReverse' | 'IsBrandedFor' | 'Variety' | 'AggregatesTo' | 'CanBeUpgradedTo' | 'IsAlternativeTo'

    const test = (val:valueT)=>  Match.value(val).pipe(
    Match.when('IsA', (v) => v),
    Match.when('IsAReverse', constant('IsA' as const)),
    Match.when('DerivedFrom', (v) => v),
    Match.when('DerivedFromReverse', constant('DerivedFrom' as const)),
    Match.when('IsBrandedFor', (v) => v),
    Match.when('Variety', (v) => v),
    Match.when('AggregatesTo', (v) => v),
    Match.when('CanBeUpgradedTo', (v) => v),
    Match.when('IsAlternativeTo', (v) => v),
    Match.exhaustive
  );
