Struggling to merge these two arrays? Look no further! By comparing the parent id to child parentsId, you can effortlessly push the second array as an extra property to its parent. Save yourself hours of frustration and achieve your desired output with a little help.
Array 1
const parent = [
{
id: 1,
name: 'john',
age: 32,
},
{
id: 2,
name: 'jane',
age: 44,
},
];
Array 2
const child = [
{
parentId: 1,
name: 'mike',
age: 5,
},
{
parentId: 2,
name: 'michelle',
age: 6,
},
{
parentId: 2,
name: 'morgan',
age: 7,
},
];
Desired result: Populate the child elements into their respective parent objects based on parentId.
const parent = [
{
id: 1,
name: 'john',
age: 32,
children: [
{
parentId: 1,
name: 'mike',
age: 5,
},
],
},
{
id: 2,
name: 'jane',
age: 44,
children: [
{
parentId: 2,
name: 'michelle',
age: 6,
},
{
parentId: 2,
name: 'morgan',
age: 7,
},
],
},
