Why my json is returning attached with Promise in nodejs function?

Question

I have normal function call in server file.

let Val = fileName.load();

In Another file:

 const load = async function(){
  getVal = await getall();
  return getVal
 }

But I'm getting the response like,

 Promise{
  [{Values: valexampl}]
  }

Why my response is getting attached with Promise here. Kindly help me to understand

The function with async keyword in front of function definition returns the Promise type value.

So to get the value, you need to use await keyword like

let Val = await fileName.load();

The second piece of code is [pretty useless](https://stackoverflow.com/questions/23667086/why-is-my-variable-unaltered-after-i-modify-it-inside-of-a-function-asynchron) – VLAZ Oct 21 '20 at 10:34
@Derek I cannot use await in the initial function. Even if I remove async also I'm getting the same response. Is there any other way? Please help. – Priyanka Oct 21 '20 at 10:50

Then you need to use like this. fileName.load().then((res) => { let Val = res; }) and inside `then` callback, do the rest. – Derek Wang Oct 21 '20 at 10:52
