How to get data from an object array to another object array ? Javascript

Question

let objArray = [ {value:null} , {value:null}];
let dataArray= [{0:12},{1:23}];

How can I get the data from dataArray to assign to 'value' in objArray ? I want to obtain an object array like below:

objArray = [{value:12},{value:23}];

Answer 1

You can do this.

let objArray = [ {value:null} , {value:null}];
let dataArray= [{0:12},{1:23}];

const result = objArray.map((item, index) => {
  item.value = dataArray[index][index]
  return item;
})

console.log(result);

Answer 2

it is pretty simple. You can use assign property values of dataArray to objArray.

objArray[0].value = dataArray[0][0]; //Note: I used bracket notation instead of dot (.) notation for accessing objects in dataArray
objArray[1].value = dataArray[1][1];

You can also iterate (loop) through arrays to assign values, but let it be practice for yourself to learn.

Good luck!
