Angular 4 proper way to cast http response

Question

I\'ve created a service in Angular 4 and I\'m fetching data via REST/JSON (new to Angular) using this code:

Interface

export interface IItem {
    Id

You'd probably want to run a few mapping utilities

http.get(url)
.map(response => response.json())
.map(response => response.d.results)
.map(results => results.map(item => return Object.create(IItem, item))
