title: Deep copying objects in angular?
body: <p>I wonder if there is away to avoid copying references to objects when you need to create a simple object which has an array of embedded objects.The situation is as follow: I have server which accepts a JSON and applies some logic then stores the object in DB. lets say my form is for saving teams in DB. The server accepts team as json. the team has an array of TeamMember objects, my form has a simple field to enter team member info and add it to team teamMembers array. Now here is the problem, when I add a team member to array list and want to add another team member when I type into the field the added member is changed also !. I know the reason </p>
  
  <pre><code>$scope.addTeamMember=function(teamMember){
     $scope.team.teamMembers.push(teamMember);
  }
  </code></pre>
  
  <p>and it is because I put same reference into the teamMembers array so I have same object added several times. 
  to avoid this I should create a new team member object, copy all teamMember properties and and add it the array. </p>
  
  <pre><code> $scope.addTeamMember=function(teamMember){
         var newTeamMember; /*&lt;--- copy teamMember */
         $scope.team.teamMembers.push(newTeamMember); /*and add newTeamMember*/
      }
  </code></pre>
