删除数组对象 相同的值 制定数组对象

var a = [
    {
        id: 1,
        name: 'hong'
    },
    {
        id: 2,
        name: 'huang'
    },
    {
        id: 3,
        name: 'lan'
    }
]

var b = [
    {
        id: 1,
        name: 'hong'
    },
    {
        id: 2,
        name: 'lan'
    },
    {
        id: 4,
        name: 'lv'
    }
]

b.forEach(item => {
    a = a.filter(a => a.id != item.id)
})
console.log(JSON.stringify(a))
