I have an array of objects that i need in a particular format. Currently it contains it's nested in such a way that it contains unwanted keys and container objects.
badArray = [
{
"college": {
"id": 1,
"location": "Victoria",
"rating": 10,
"alumni": [
{
"alumni_id": 1,
"alumni_position": 1
},
{
"alumni_id": 2,
"alumni_position": 3
},
]
}
},
{
"college": {
"id": 2,
"location": "New York",
"rating": 9,
"alumni": [
{
"alumni_id": 5,
"alumni_position": 7
}
]
}
}
]
What I'd like to get to is a less nested object with the following structure
goodArray = [
{
"id": 1,
"location": "Victoria",
"rating": 10,
"alumni": [
{
"alumni_id": 1,
"alumni_position": 1
},
{
"alumni_id": 2,
"alumni_position": 3
},
]
},
{
"id": 2,
"location": "New York",
"rating": 9,
"alumni": [
{
"alumni_id": 5,
"alumni_position": 7
}
]
}
]
I can remove the unwanted key using
Object.values(badArray[0])
But I'm really struggling to find a way to remove the unwanted outer container aswell.
Any help REALLY appreciated
You can just do an array map and return your desired array in this situation instead of trying to delete keys
badArray = [
{
"college": {
"id": 1,
"location": "Victoria",
"rating": 10,
"alumni": [
{
"alumni_id": 1,
"alumni_position": 1
},
{
"alumni_id": 2,
"alumni_position": 3
},
]
}
},
{
"college": {
"id": 2,
"location": "New York",
"rating": 9,
"alumni": [
{
"alumni_id": 5,
"alumni_position": 7
}
]
}
}
]
let goodArray = badArray.map(el => el.college)
console.log(goodArray)Logic
Array.map through array.Object.values of each Object in the arrayI have considered you have only one key in each object of the array. This solution will work for any valye for your key.
Working Fiddle
const badArray = [
{
college: {
id: 1, location: "Victoria", rating: 10,
alumni: [
{ alumni_id: 1, alumni_position: 1 },
{ alumni_id: 2, alumni_position: 3 },
],
},
},
{
college: {
id: 2, location: "New York", rating: 9,
alumni: [
{ alumni_id: 5, alumni_position: 7 },
],
},
},
];
const goodArray = badArray.map(item => Object.values(item)[0]);
console.log(goodArray);If your key is constant as "college" you can perform this as.
const goodArray = badArray.map(item => item.college);
