If I have typescript class that has the following data:

private _initialNames: any;

async getData(): Promise<any> {
   
   const resp = await fetch(url);
   const { data } = await resp.json();

   this._initialNames = data.reduce(
        (acc: any, curr: any) => ({
            ...acc,
            [curr.name]: {
                found: curr.found,
                age: curr?.age,              
            }
        }),
        {}
    );   
    
    return this._initialNames;
}

when I call this function, why do I use await getData(); since it's returning an array, not a Promise? I know I have to use async since I am awaiting a fetch inside but when I call the actual function , do I still await it?
