Typescript如何安全地将枚举转换为另一个枚举？

enum EnumA {
  Value1,
  Value2,
  Value3,
}

enum EnumB {
  NewValue1,
  NewValue2,
  NewValue3,
}

const enumAValue: EnumA = EnumA.Value1;
const enumBValue: EnumB = enumAValue as EnumB;

type EnumMapping = {
  [key in EnumA]: EnumB;
};

const enumMap: EnumMapping = {
  [EnumA.Value1]: EnumB.NewValue1,
  [EnumA.Value2]: EnumB.NewValue2,
  [EnumA.Value3]: EnumB.NewValue3,
};

const enumAValue: EnumA = EnumA.Value1;
const enumBValue: EnumB = enumMap[enumAValue];
