# --description--

Use a `for` loop to log the `name` of every astronaut in the `sorted` array.

# --hints--

You should use a `for` loop to iterate through the `sorted` array and log the `name` of each astronaut.

```js
const cleaned = __helpers.removeWhiteSpace(__helpers.removeJSComments(printCrewSummary.toString()))
assert.match(cleaned, /for\s*\(/);
function captureConsole(fn) {
  const logs = [];
  const originalLog = console.log;
  console.log = (...args) => logs.push(args.join(" "));
  try {
    fn();
  } finally {
    console.log = originalLog;
  }
  return logs;
}
const testCrew = [
  { name: "Andy", priority: 3 },
  { name: "Bart", priority: 8 },
  { name: "Caroline", priority: 4 },
  { name: "Diego", priority: 1 },
  { name: "Elise", priority: 7 },
  { name: "Felix", priority: 6 },
  { name: "Gertrude", priority: 4 },
  { name: "Hank", priority: 2 },
  { name: "Irene", priority: 5 },
  { name: "Joan", priority: 1 }
];
const logs = captureConsole(() => printCrewSummary(testCrew));
const expectedOrder = [
  "Bart",
  "Elise",
  "Felix",
  "Irene",
  "Caroline",
  "Gertrude",
  "Andy",
  "Hank",
  "Diego",
  "Joan"
];
assert.strictEqual(
  logs.length,
  expectedOrder.length,
  "You must log each astronaut's name exactly once"
);
assert.deepEqual(
  logs,
  expectedOrder,
  "Names must be logged in descending priority order"
);
```
