How to merge and group arrays of objects by ids?

Question

I need to unite two arrays with objects with equal id.

const arr1 = [{id: 1, name: 'John'}, {id: 10, name: 'Janny'}, {id: 22, name: 'Mark'}];
const arr2 = [{id: 1, name: 'John', phone: '111'}, {id: 15, name: 'Nick'}, {id: 22, name: 'Mark'}];

The result should be

[
  {id: 1, name: 'John', phone: '111'}, 
  {id: 15, name: 'Nick'},
  {id: 22, name: 'Mark'},
  {id: 10, name: 'Janny'}
]

I tried to use lodash _.isEqual(arr1, arr2) but it's not working, because {id: 1, name: 'John', phone: '111'} is not equal to {id: 1, name: 'John'}.

Answer 1

here is a very stupid and long way to do it:

const arr1 = [{id: 1, name: 'John'}, {id: 10, name: 'Janny'}, {id: 22, name: 'Mark'}];
const arr2 = [{id: 1, name: 'John', phone: '111'}, {id: 15, name: 'Nick'}, {id: 22, name: 'Mark'}];
let newArr = [];
firstLoop: for(let i=0; i < arr1.length; i++){
    for(let j =0; j < arr2.length; j++){
        if(arr1[i].id == arr2[j].id){
            newArr.push({...arr1[i], ...arr2[j]})
            continue firstLoop;
        }
    }
    newArr.push(arr1[i])
}
firstLoop: for(let i=0; i < arr1.length; i++){
    for(let j =0; j < arr2.length; j++){
        if(arr2[i].id == arr1[j].id){
            // newArr.push({...arr1[i], ...arr2[j]})
            continue firstLoop;
        }
    }
    newArr.push(arr2[i])
}
console.log(newArr);
