Also, you need to position your scatter operator at the beginning of the fully qualified name.
And you need to assign "hobbies", the "reduce" should be applied to the "customers" array.

Courses Plus Student 9,178 PointsIs this right? hobbies = customers.reduce((arr,arrf)=> [...arr, arrf.personal.hobbies...,[]);

231,184 PointsThe scatter operator goes in front of the term, like you have on the first one.

231,184 PointsI mean it should go in front of the entire term (not just the property name). Plus it looks like you're missing a closing bracket ("]").
