title: Change value in an observable
body: <p>If I have an observable <code>student: Observable&lt;Student&gt;</code> where <code>Student</code> has the parameter <code>name: string</code> is set to <code>Jim</code>, How can I change the value of <code>name</code> in the <code>students</code> observable to be <code>Bob</code>?</p>
  
  <p>Edit:</p>
  
  <p>Is <code>student.map(student =&gt; student.name = 'Bob')</code> supposed to work. Because if yes then there is something else wrong with my program.</p>
