title: VueJS Stop observer watching a temporary variable
body: <p>I am having a problem with VueJS and Observer objects. I am assigning part of my object to a temporary variable to use later. Then resassign the original part of my object with new data and after 8 seconds revert it back to its original state that I stored in my temporary variable. </p>
  
  <p>I have this Object linked to a list view which renders these 2 different states differently. </p>
  
  <p>I want to stop the observer from observing my temporary variable but I cant work out how. </p>
  
  <p>Below is the code I currently have:</p>
  
  <pre><code>var temporary = core_data.map_data[data.selected]; //This is the variable I dont want to be observed.
  
  core_data.map_data[data.selected].colour = data.colour;
  core_data.map_data[data.selected].message = data.message;
  core_data.map_data[data.selected].type = "ping";
  setTimeout(
      function () {
          core_data.map_data[data.selected] =temporary;
  
          // console.log(core_data.map_data);
      }, 8000);
  </code></pre>
