在数组中过滤id重复的对象并组成新的数组

const data = [
            { id: 1, name: '张三', age: 15, },
            { id: 2, name: 'John', age: 18, },
            { id: 3, name: '李四', age: 18, },
            { id: 1, name: '张三', age: 15, },
            { id: 4, name: 'Jack', age: 18, },
            { id: 5, name: '王五', age: 10, },
            { id: 4, name: 'Jack', age: 18, },
            { id: 2, name: 'John', age: 18, },
        ];
 
let hash = {}; 
data.reverse()       //数组翻转
const data2 = data.reduce((preVal, curVal) => {
    hash[curVal.id] ? '' : hash[curVal.id] = true && preVal.push(curVal); 
    return curVal 
}, [])
console.log(data)
console.log(data2)

获取id相同的最后一个对象，并和其他已去重的对象组成新的数组
