title: How does one reassign variables in an object?
body: <p>For a class I'm taking, I need to reassign an object's properties to "Unknown". Here is the sample problem: </p>
  
  <pre><code>//In the function below, "person" will be passed in as an object that represents a person with properties such as name, age, gender, etc.
  //Loop through all the properties of the object and set each value equal to "Unknown"
  //For example, if "person" is {name: "Dolph L.", age: 33} then the function would return {name: "Unknown", age: "Unknown"}
  
  function describePerson(person) {
      //code here
  }
  </code></pre>
  
  <p>If I'm understanding is correctly, it says that I must loop through the object and reassign it's properties to "Unknown". What I've been trying to do is this: </p>
  
  <pre><code>function describePerson(person) {
      for (var prop in person) {
         if (prop) {
             return "Unknown";
         }
      } 
  }
  </code></pre>
  
  <p>I'm very new to Javascript and could really use some help here. </p>
  
  <p>Thanks</p>
