等待异步功能，直到返回数据

Question

我有此代码：

let getUserPosts = async (id: number) =>{
const access =  new DatabaseAccess();
await access.init();
let videosArray: any = [];
const subscriptions = await access.getSubscriberTargetIds(id);
// @ts-ignore
 await subscriptions.forEach(async function(thing: any){
    const posts = await access.getUserPosts(thing.target_id)
    videosArray = [...videosArray, ...posts]
    console.log(videosArray)//console logging here works fine
});
 console.log(videosArray)//here i have an empty array
while(videosArray == []){
    console.log('waitin till that')
}
return videosArray
}

我需要将其返回到主要的get函数，以向用户显示供稿作为响应。 该代码正在Deno上运行，但我确定它适用于Node。
