我有5个矩对象的数组：
const list = [moment(a),moment(b),moment(c),moment(d),moment(e)];
我可以记录星期几（1-7 /周一至周日）：
const daysOfTheWeek = list.map(v => v.day());
我得到：
[ 4, 1, 3, 5, 1 ]
现在，我这样做：
dates.reduce((a, b) => {
assert([1, 2, 3, 4, 5].includes(a.day()), 'day is a saturday or sunday, wrong.');
assert(b > a, 'date is not forward in time.');
});
但是a未定义，为什么在reduce调用中未定义a或b？
出现错误：
TypeError: Cannot read property 'day' of undefined
我在这里俯瞰什么？
答案 0 :(得分：1)
是的，我忘了从reduce回调中返回一些东西，这就是为什么下一个值未定义的原因。
这更好：
