js数组对象去重

var arr = [
    {name:'uzi',color:'blue'},
    {name:'pdd',color:'white'},
    {name:'mlxg',color:'orange'},
    {name:'uzi',color:'red'},
]

let hash = {};
var newArr = arr.reduce((item, next) => {
    hash[next.name] ? '' : hash[next.name] = true && item.push(next);
    return item
}, []);
console.log(newArr);

第二种：reduce()
