  TYPE_2 = 2,
}

enum TestingStringEnum {
  TYPE_0 = 'TYPE_0_VALUE',
  TYPE_1 = 'TYPE_1_VALUE',
  TYPE_2 = 'TYPE_2_VALUE',
}


// Should contain exactly: ['TYPE_0', 'TYPE_1', 'TYPE_2']
const numericNames: string[] = listEnumMemberNames(TestingNumericEnum);

// Should contain exactly: ['TYPE_0', 'TYPE_1', 'TYPE_2']
const stringNames: string[] = listEnumMemberNames(TestingStringEnum);

//   {name: 'TYPE_0', value: 0},
//   {name: 'TYPE_1', value: 1},
//   {name: 'TYPE_2', value: 2},
