如何將屬性添加到數組中的現有 object

Question

例如這是原始數組

[
 {name:xyz,id:123 },
 {name:abc,id:232},
] 

現在這是另一個數組

[
 {value:'anything'},
 {value:'anything12312'}
]

現在在新數組或原始數組中 output 應該是這個

[
 {value:'anything',name:xyz,id:123},
 {value:'anything12312', name:abc,id:232}}
]

我怎樣才能做到這一點

Answer 1

你是說這樣？？

使用map ，索引和傳播為：

 let a = [ {name:"xyz",id:123 }, {name:"abc",id:232}, ] let b = [ {value:'anyrhing'}, {value:'anything12312'} ] let res = a.map((el,idx)=> ({...el,...b[idx]})); console.log(res)

Answer 2

使用 object 解構。

const arr1 = [
 {name:'xyz',id:123 },
 {name:'abc',id:232},
] 

const arr2 = [
 {value:'anyrhing'},
 {value:'anything12312'}
]

const arr3 = [];
for(let i=0;i<arr1.length;i++)
  arr3.push({...arr2[i],...arr1[i]});

Answer 3

A1=[
    {name:"xyz",id:123 },
    {name:"abc",id:232},
   ];
A2=[
    {value:'anyrhing'},
    {value:'anything12312'}
   ];

obj1={
    ...A2[0],
    ...A1[0]}

//another method to merge objects

obj2=Object.assign(A2[1],A1[1]);

//The result you needed

A3=[obj1,obj2];
