3请筛选出数组中大于60分的学生的分数 筛选出来后计算总和 const persons = realname张三score60 realname李四score20 realname王五score90 realname赵六score59 realname李七score80

const scores = persons.filter(person => person.score > 60).map(person => person.score); const sum = scores.reduce((acc, cur) => acc + cur, 0); console.log(scores); // [90, 80] console.log(sum); // 170
