Hello i am trying to do something that sounds very simple but i cant wrap my head around it. i got this interface



    export interface CurrentStanding
{
TournamentName: string
ExternalId: string
Points: number
}


and all i really want to do is initiate this in my main class and pass it down to my component that need it which currently looks like this.



import { CurrentStanding } from "../models/CurrentStanding"
import { LeaderboardBar } from "./bar/LeaderboardBar";

export interface Props
{

}

export interface State
{
currentStanding: CurrentStanding
}

/**
* Top component. Contains most of the app state and coordinates communication between the children.
*/
export class Main extends Component<Props, State>
{
constructor(props: Props)
{
super(props);

this.state = {
currentStanding:
};
}
render()
{

return (
<div>
<LeaderboardBar
onClick={this.onTermsPressed.bind(this)}
currentStanding={this.state.currentStanding}
/>
</div>
)
}


But the problem here is that i cant figure out how to initate it in the state were it right now only says "currentStanding:" what can i write after the : i only want an empty CurrentStanding that i fill from the component it gets sent down to.
