js 删除两个数组中id相同的对象

let arr1 = [{id:'1',name:'json'},{id:'2',name:'book'} ]
let arr2 = [{id:'1',name:'json',age:'15'},{id:'2',name:'book',age:'16'},{id:'3',name:'ani',age:'17'}] 

//ES6的方法

let add = arr2.filter(item => !arr1.some(ele=>ele.id===item.id));

cosnole.log(add);

//ES5的方法

for (var i=0; i<arr2.length; i++) {  
     for (var j=0; j<arr1.length; j++) {  
           if (arr2[i].id == arr1[j].id) {  
                arr2.splice(i, 1);    
           }  
     }  

}
