The console should display four lines that include both the property name and value. For example: 'instrument: piano'.

script.js 
const composer = {
  name: 'Edward Ellington',
  nickname: 'Duke',
  genres: ['jazz', 'swing'],
  instrument: 'piano'
};
for(let prop in composer)
  console.log(prop)
console.log(`${prop}: ${composer[prop]} `)

The issue here is syntax (depending on if Treehouse is using strict syntax in their editor) and the fact that you are leaving the previous solution there, as well as the extra added space in your solution.

So one issue at a time:

  1. Syntax, make sure your for..in loop has brackets
for(let prop in composer) {
}
  1. Remove the previous solution, you should only be logging what they are asking you to log which is now, the property and value.
for(let prop in composer) {
    console.log(`${prop}: ${composer[prop]}`);
}
  1. You added a space at the end of the ${composer[prop]} like that. Remove it, Treehouse's solutions tend to be very specific about the syntax of the solution.
