Take a look at the following code snippet:
export enum ResponseCodes {
'Network error' = 5003
}
const code: ResponseCodes = 4000 // This does not result in an error
const code: ResponseCodes = ResponseCodes['Network error']
Why doesn't the enum have a specific key and why is there no error?
ResponseCodes compiles to
{
5003: "Network error",
Network error: 5003,
}
This explains why const code: ResponseCodes = 4000 does not trigger an error. It's a limitation of numerical enums, where every number can be assigned to the enum.
Is there a way to enforce using the following syntax:
