title: display a list of custom data in anugular
body: <p>As a learner I am able to display the list of custom objects in a display page in angular. But I want to know the efficient way to decode the IDs corresponding to its values in that display page. To explain the same lets say my Backend service is returning a list of Custom Object name TestData which consist of fields like Id, content, categoyId, productId etc.</p>
  <p>TestData {
  Id: number,
  content: string,
  categoyId: number,
  productId: number,
  }
  The backend REST service is returning categoyId &amp; productId as a int value, but I want to show the corresponding names in display page. Any suggestion and advise is highly appreciated.</p>
