只需使用数组查找方法:https://ramdajs.com/docs/#find

拉姆达：

const items = [{
  cardLast4Digits: '0664',
  cardType: 'GIFT_CARD'
}, {
  cardLast4Digits: '5551',
  cardType: 'CREDIT_CARD'
}];
R.find(R.propEq('cardType', 'GIFT_CARD'))(items);

ES6:

const items = [{
  cardLast4Digits: '0664',
  cardType: 'GIFT_CARD'
}, {
  cardLast4Digits: '5551',
  cardType: 'CREDIT_CARD'
}];

const result = items.find(item => item.cardType === 'GIFT_CARD');
console.log(result);
