Does anyone have an example of a custom promise within suitescript 2.0

```function createRecord(type) {
  return new Promise(function(resolve) {
    record.create.promise({type: type}).then(resolve);
  });
}

createRecord(record.Type.CUSTOMER).then(function(newRecord) {
  // Do more stuff
});```

That's a super simple custom promise. It's equivalent to this:
```record.create.promise({type: record.Type.CUSTOMER}).then(function(newRecord) {
  // Do more stuff
});```

that only works because record.create has a promise

I am trying to do this for a custom function

You can't just convert synchronous code into asynchronous.

custom function performs multiple searches returns a number, so in other words as mentioned in the other thread bellow, I have to rewrite the whole function to utilize promises on the searches themselves

JavaScript is single threaded, so it can only work on one execution at a time.

it's not really accurate to say JavaScript is single threaded these days.
