Я хочу зациклить элементы (внутри тела), и я попробовал что-то вроде этого: 

var dataStr = JSON.stringify(response);
var dataPrs = JSON.parse(dataStr);
var dataList = JSON.stringify(dataPrs.items);
dataStr = JSON.stringify(dataList);
dataPrs = JSON.parse(dataStr);
dataListPrs.forEach( console.log(dataPrs.htmlLink) );

, а также: 

cons items = data.items;
items.forEach(x => console.log(x.htmlLink))

, а также: 

var dataStr = JSON.stringify(response);
var dataPrs = JSON.parse(dataStr);
var body = dataPrs.body.items;
console.log("body", body);
const items = response.items;
console.log("items", items);
items.forEach(x => console.log(x.htmlLink));

но items всегда undefined

Я решил, это было на @Always Sunny и на @Karl Galvez way;также помогло заявление @Sandeep P, потому что я был на .then

большое спасибо всем, кто помогал и связывал.

Если ответ исходит от Promise, вам может потребоваться включить response.data.items

Исходя из того, что вы указали, я ожидаю, что эти строки будут работать: 

const items = response.items;
console.log("items", items);
items.forEach(x => console.log(x.htmlLink));

Это сработало в моем тесте, когда я установил response в JSON, который вы указали.Так что я бы ожидал, что response - это не то, что вы думаете, когда запускается этот код.

Вы можете сделать это с помощью forEach(), чтобы получить htmlLinks от объекта json, как показано ниже -
