从二维键值数组获取值，组成新的二维键值数组，怎么实现啊

Question

从var data3 = [{name: 'Apples',y: 1},{name: 'Oranges', y:2, drilldown: 'third-leves'},{name: 'peach', y:3, drilldown: 'third-leves'}];
获取name 和 y 的值生成一个新的二维键值数组 var arr=[]    变成这样  arr=[{'Apples',1}{'Oranges',2},{'peach',3},]   

Answer 1

[{'Apples',1}{'Oranges',2},{'peach',3},] 这不是二位数组
var data3 = [{name: 'Apples',y: 1},{name: 'Oranges', y:2, drilldown: 'third-leves'},{name: 'peach', y:3, drilldown: 'third-leves'}];
var arr = [];
var data3 = [{name: 'Apples',y: 1},{name: 'Oranges', y:2, drilldown: 'third-leves'},{name: 'peach', y:3, drilldown: 'third-leves'}];
var arr = [];
data3.forEach(function(item){
 arr.push([item.name,item.y]);
})
console.log(arr)

Answer 2

var data3 = [{name: 'Apples',y: 1},{name: 'Oranges', y:2, drilldown: 'third-leves'},{name: 'peach', y:3, drilldown: 'third-leves'}];
        data3=data3.map(item=>({[item.name]:item.y}));
        console.log(data3);

Answer 3

var data3 = [{name: 'Apples',y: 1},{name: 'Oranges', y:2, drilldown: 'third-leves'},{name: 'peach', y:3, drilldown: 'third-leves'}];我想给里面的每个{}里面添加一个相同的 键值对   title：'标题'   怎么实现啊
谢谢哈

Answer 4

data3.forEach(function(item){
item.title = "标题";
})
console.log(data3)
