Interface Oof { yikes_enabled: boolean yikes_string: string |

Question

Interface Oof { yikes_enabled: boolean yikes_string: string |

undefined
}

I'm sure that if yikes_enabled === true then yikes_string won't be undefined
Can I somehow make TS check that? If yes, how to Google it 😵‍💫

Thank you! I have more properties in my actual interface, should I switch whole interface to type? Also when to use type vs interface? I use types mainly for stuff like type Boof = “borf” | “bark” | “woof”

I don't use interface at all. There's nothing interface can do that type can't.
