// 数组对象排序方法 export function compare(property) { return function (a, b) { const value1 = a[property] const value2 = b[property] return value2 - value1 // 正序 return value1 - value2 降序 } }, let arr = [ {name: '小明', age: 18}, {name: '小花', age: 20}] 比较两个人的年龄大小： let newArr = arr.sort(compare('age')) console.log(newArr) 计算两个人的年龄之和： let sumCount = arr.reduce((ageSum, currStudent) => { return ageSum + Number(currStudent.age); }, 0) console.log(sumCount)
