How can I push elements out of a forEach() context?

Congrats on your first post ever!

It's a super classic question though, how to use an asynchronous function in a loop. With .forEach you can't, but you can using await in a for loop :

let promisesArray = [];

for (let object of ObjectJSON.array) {
  if (object.key !== "foo") continue;

  const response = await functionBar();

  promisesArray.push(
    `Object: ${object.key}  |  ${object.someOtherKey}`
  );
}

resolve(promisesArray);

Using await will probably require your function to be marked as async (async function doSomething() { ... )
