Merging an object to a list of objects

Question

Hi all I’m trying to merge a object into each object inside an array something like this

Object to be inserted/merged:

Object1 : {‘name’:””}

The array of objects into which above needs to be merged

Array : [{‘dob’ : 22011991}, {‘class’ : 8208}]

And, the expected output:

[ {‘name’:””,’dob’ : 2201191},  {‘name’:””,‘class’ : 8208}]

You haven't provided enough information to understand what you want to do. — Yogi, Apr 13 '22 at 16:11
Please try this: `const updatedArray = origArray.map(obj => ({ ...obj, name: '' }));` — jsN00b, Apr 13 '22 at 16:31

const object1 = {name: ''};
const arr = [{ dob: 22011991 }, { class: 8208 }]
const merged = arr.map(item => ({ ...item, ...object1 }));

Here is something similar, but if you just want to push one key from object1.

const object1 = {name: ''};
const arr = [{ dob: 22011991 }, { class: 8208}]

const merged = [];
for (let i = 0; i < arr.length; i++) {
  const currentObjInArr = arr[i];
  merged.push({...currentObjInArr, ...object1})
};

console.log('merged: ', merged);

One possible solution by using .map and ... spread.

console.log(
  [{dob : 22011991}, {class : 8208}]
  .map(obj => ({
    ...obj,
    ...{ name : ""}
  }))
);
