Why am I getting this message? Make sure you're using the `let` (or `const`) keyword in the `for...in` loop.

script.js 
const composer = {
  name: 'Edward Ellington',
  nickname: 'Duke',
  genres: ['jazz', 'swing'],
  instrument: 'piano'
};

for (let prop in composer) {
console.log(prop);
}

for (let prop in composer) {
console.log (`${prop}: ${composer[prop]}`);
}

Hi Angelica,

actually you did it perfectly right and there is no mistake.

When you add the second for loop just make sure you delete the first for loop - otherwhise it will not pass. ;-)

So they only want you to have ONE for loop

I checked it, but let me know if it works for you too.

Needless to say, the error message is not very helpful in this case. ;-)

Blessings from Berlin and happy java-scripting, Nils
