How can I assign a type to an array of objects?

The Error is: Type '{ id: string; title: string; content: string; }[]' is missing the following properties from type 'InitialState': id, title, contentts(2739)

interface InitialState {
    id: string,
    title: string,
    content: string
    
}

const initialState:InitialState = [
   {id: '1', title: 'post title', content: 'the fack content'},
   {id: '1', title: 'post title', content: 'the fack content'},
]
