I have 2 enums:
enum Insurer {
PREMERA = 'premera_blue_cross',
UHC = 'united_health_care'
}
enum ProductSource {
PremeraBlueCross = 'premera_blue_cross',
UnitedHealthCare = 'united_health_care'
}
I try check if array of Insurer includes ProductSource:
const insurerArr: Insurer[] = [Insurer.PREMERA, Insurer.UHC]
insurerArr.includes(ProductSource.PremeraBlueCross)
But got an error from the TS compiler:
Argument of type 'ProductSource' is not assignable to parameter of type 'Insurer'.
There is a way to compare without do a casting to string and then to the other enum?
You may want to consider to switch to type instead of enum:
type Insurer = 'premera_blue_cross' | 'united_health_care';
type ProductSource = 'premera_blue_cross' | 'united_health_care';
const insurerArr: Insurer[] = ['premera_blue_cross', 'united_health_care'];
insurerArr.includes('premera_blue_cross');
