Using OR in type interface typescript

Question

I have an array in which every index item can be either IBusinessDetailCompetitor or ICustomerCompetitorInstant

So can I do something ilke this
customerCompititorArray: (IBusinessDetailCompetitor[] | ICustomerCompetitorInstant[])

But this is giving errror. Please help.

Answer 1

The item in array should be union types :

interface IBusinessDetailCompetitor {
    a: string
}
interface ICustomerCompetitorInstant {
    b: string
}

const customerCompititorArrayCorrect: Array<IBusinessDetailCompetitor | ICustomerCompetitorInstant> = [{a: '1'}, {b: '2'}]
