Async / Await returning Promise <pending> instead of values

Hi,

There seems to be an issue with Async/Await handling. Code below:

async function getData() {
  console.log('logging');
  const test = await CSVToJSON().fromFile('./data/hans-puns.csv');

  return test;
}

const data = getData();

console logging data shows a Promise

I think I might have been unclear in my earlier comment. I never wanted you to try to await outside an async function. You can’t do that in current Node. What you need to do is wrap your await call inside an async function, and then call that async function in the top-level of your script. If you just try to immediately use the output of the async function, it isn’t going to be useful, because it’s going to be a Promise. But I think people got the impression that I was suggesting to use the given code as-is but only adding await, which is not what I meant to say at all.

You’re trying to do something like this:

const data = asyncFunc();
console.log(data); // will give you something like Promise { }

You read my comment and understandably thought I meant to do this:

const data = await asyncFunc(); // will error
console.log(data);

What I actually meant was to do this:

async function run() {
  const data = await asyncFunc();
  console.log(data); // will print your data
}

run() // run the async function at the top-level, since top-level await is not currently supported in Node

You don’t need to await on the final run() call, since Node won’t exit until its event loop is empty.

async functions return promises. you need to do const data = await getData() – unless you intend to set data at the top level of the code, in which case you can’t await on getData and need to console.log from inside getData, or log from a different function that calls await getData() inside it.
