如果 object 集有一个 object 属性创建一个数组

Question

I have a response value which is dynamic which i need to store in redux state,

Response consist of array of object and and name ex:

{data:[
 {name:"abc",age:"10",id:"10"}
 {name:"abc",age:"15",id:"20"}
 {name:"def",age:"15",id:"20"}
 ]
 name: "abc"
}

So if the name is same I need to create array with the name.

Expected:

abc:[
   {name:"abc",age:"10",id:"10"}
   {name:"abc",age:"15",id:"20"}
]

something I tried

data.map(function(o) {
       if(data.name ==o.name)
        return name[o];
 });

If you're wanting a new object with a key of the name property you could try something like this

 const response = { data: [{ name: "abc", age: "10", id: "10" }, { name: "abc", age: "15", id: "20" }, { name: "def", age: "15", id: "20" }, ], name: "abc" } const createSet = (someData) => { let key = someData.name let data = someData.data.filter(e => e.name === key) return { [key]: data } } console.log(createSet(response))

You can extract duplicated using reduce and filter :

 var data = { data:[ {name:"abc",age:"10",id:"10"}, {name:"abc",age:"15",id:"20"}, {name:"def",age:"15",id:"20"} ], name: "abc" } const lookup = data.data.reduce((a, e) => { a[e.name] = ++a[e.name] || 0; return a; }, {}); console.log(data.data.filter(e => lookup[e.name]));
