import fetchMock from 'fetch-mock'; import querystring from 'querystring'; // A mock item list... const items = new Array(100) .fill(null) .map((v, i) => `Item ${i}`); // The same filter and sort functionality // as the previous example, only it's part of the // API now, instead of part of the React component. const filterAndSort ...
