【TypeScript】九、枚举类型

1. 数字枚举

enum A {
    red,
    green,
    blue,
}
console.log(A.red);
console.log(A.green);
console.log(A.blue);

2. 增长枚举

enum A {
    red=1,
    green,
    blue,
}
console.log(A.red);
console.log(A.green);
console.log(A.blue);

3. 反向映射

enum Types {
    success
}
let success = Types.success
console.log(Types[success]);
