Stopping loop when condition is met

I would like to loop through the whole array, and stop when my if-condition is met, then put the value in my var checked.

If the if-condition is not met, the var should be set false.

When I put the break my script outputs false, which it shouldn't since 2002 exists in the array.

subscriber = [2001, 2002, 2004]

for(i = 0; i < subscriber.length; i++) {
  if (subscriber[i].ID == '2002') {
    checked = 'true';
    break; //added break here
  } else {
    checked = 'false';
  }
  Write(checked);
}

(please don't mind the properties of the object e.g. ID)

It looks like your subscriber array isn't formed correctly. Your for loop seems to indicate that each element in subscriber is an object with an id property.

Working off this assumption, you can optimize your code as follows:

const subscribers = [{ id: 2001 }, { id: 2002 }, { id: 2004 }];
const checked = subscribers.some(subscriber => subscriber.id === 2002);

The some function will return true if anything in the array passes the check.
