javascript - not able to execute the promise from array one by one

Question

I found that I cannot resolve the promises one by one.

This is my code

const promises = mkt.map((marketItem) => {
  return context.program.account.chain
    .fetch(marketItem[0].instrument)
    .then((instrumentRes) => {
      return Test(context, marketItem[0]).then(
        testResult => {
          return Promise.all([
            functionA(),
            functionB(),
          ]).then((result) => {
            return result
          });
        }
      );
    });
});
console.log(promises)
for (let i=0; i < promises.length; i++) {
  const val = await promises[i]();
  console.log(val);
}

error

promises[i]() is not a function

Why is that?How can I solve it?

Answer 1

Just removing the () from the await call should already work.

  const val = await promises[i];

However keep in mind that all the promises have already been "started" (I don't know a better word for that) at that point and you're just retrieving the results or an error with the await call.
