After reading through https://github.com/Microsoft/TypeScript/issues/7642 and https://github.com/Microsoft/TypeScript/pull/9407, it seems that enum literal types are supposed to work. However, I encountered a strange issue:
const enum STATUS {
CREATED = 201,
NOT_FOUND = 404,
}
const statusCode: STATUS.CREATED = 404; // no error is shown
Is it valid to assign values to enum members in this way?
TypeScript version being used: 2.3
Can enum members be utilized in this manner?
No, the error occurs because numbers can be assigned to enums. For example:
const enum STATUS {
CREATED = 201,
NOT_FOUND = 404,
}
const why: STATUS.CREATED = 123123; // no error
const foo: 1 = 1;
const because: STATUS.CREATED = foo;
In essence, it is not considered an error as this particular scenario is not addressed by current TypeScript language design.
