TypeScript equivalent of PropTypes.array and PropTypes.object?

Question

What is the TypeScript equivalent of this?

sessions: PropTypes.oneOfType([
    PropTypes.array,
    PropTypes.object,
]).isRequired,

I translated this to the following 'point':

export type Sessions = [Object | Array];

However, I'm not sure how I should replace PropTypes.array and PropTypes.object.

Like any other type

static propTypes = {
    sessions: Array | Object
}

If session is an array of either type (but it's not what is stated in the PropTypes expression):

sessions: (Array | Object)[]

If it's not required:

sessions?: Array | Object

typeless Array can also be expressed as [].

(Object | Array)[] can also be expressed as Array<Object | Array>.

In some case Object can also be expressed as {} and this way can declare props: {a: number, b: string}

You can consider this

type TypeSessions = Object | Array;
const sessions: TypeSessions = [];
