如何在typescript中获取枚举的值

enum Colors {
  Red = 1,
  Green = 2,
  Blue = 3
}

const colorValue = Colors['Red']; // 获取枚举成员Red的值
console.log(colorValue); // 输出: 1

enum Colors {
  Red = 1,
  Green = 2,
  Blue = 3
}

const colorName = Colors[2]; // 获取枚举成员值为2的名称
console.log(colorName); // 输出: Green

enum Colors {
  Red = 1,
  Green = 2,
  Blue = 3
}

for (let color in Colors) {
  const colorValue = Colors[color]; // 获取枚举成员的值
  console.log(`${color}: ${colorValue}`);
}
// 输出:
// Red: 1
// Green: 2
// Blue: 3
