}

и я хочу сделать 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) );

Вам не нужно делать JSON.stringify и JSON.parse каждый раз.

Вам нужно JSON.stringify, только если вы хотите преобразовать объект Javascript в строку JSON

и JSON.parse толькоесли вы хотите преобразовать строку JSON в объект Javascript и получить доступ к ее значениям с помощью ключа.

Итак, все, что вам нужно:
