entity:

interface iproduct {     title: string;     showimage: boolean;     products: productdetails[]; }  class product implements iproduct {     title: string;     showimage: boolean;     products: productdetails[]; }

as per comments attaching response object

$promise:d   $$state:object   __proto__: object $resolved:true objdetails:array[3] showimage:false title:"tetsing typescropit" __proto__: object
