在javascript中将对象数组组合和过滤为单个对象

Question

 let myCurrentData = [ { _id: "D01", name: "Lunetts", profession: "shop", }, { _id: "D02", name: "Glasses", profession: "keeper", }, { _id: "D03", name: "Auros", profession: "UiiSii", }, ];

Above is my myCurrentData, I want to convert this array into a final object like the following

 let myFinalData = { D01: "Lunetts", D02: "Glasses", D03: "Auros" }

i just want to use the values of _id and name

Answer 1

 const myCurrentData = [ { _id: "D01", name: "Lunetts", profession: "shop", }, { _id: "D02", name: "Glasses", profession: "keeper", }, { _id: "D03", name: "Auros", profession: "UiiSii", }, ]; const finalObject = myCurrentData .map((eachObject) => { const { profession, name, _id } = eachObject; return { [_id]: name, }; }) .reduce((prev, current) => { return { ...prev, ...current, }; }, {}); console.log("finalObject is", finalObject);

Hope it works!

Answer 2

Use a simple loop to create a new object.

 const data=[{_id:"D01",name:"Lunetts",profession:"shop"},{_id:"D02",name:"Glasses",profession:"keeper"},{_id:"D03",name:"Auros",profession:"UiiSii"}]; const out = {}; for (const obj of data) { out[obj._id] = obj.name; } console.log(out);

Answer 3

You can achieve this using reduce and returning an object from it:

const myObj=  myCurrentData.reduce((acc,curr)=> {
    return {...acc, [curr._id]:curr.name}
  
}, {})

Answer 4

You could take advantages of the Object.entries method combined with a forEach loop to get the properties name and values and add it to your previously declare myFinalData Object. Something like this could be what you are looking for. Hope it helps, bud.

const myCurrentData = [
  {
    _id: "D01",
    name: "Lunetts",
    profession: "shop",
  },
  {
    _id: "D02",
    name: "Glasses",
    profession: "keeper",
  },
  {
    _id: "D03",
    name: "Auros",
    profession: "UiiSii",
  },
];


 const myFinalData = {}
Object.entries(myCurrentData).forEach(([k,v]) => { myFinalData[v['_id']] = v['name']})

console.log(myFinalData);
