Question: I have an object of data and I want to split it array of objects

```
let data = {
    "education_center-266": "Software House x",
    "education_center-267": "Learning Academy xyz",
    "end_date-266": "2022-01-26",
    "end_date-267": "2021-01-22",
    "start_date-266": "2021-01-26",
    "start_date-267": "1998-11-26",
    "title-266": "Web Developer",
    "title-267": "Teacher",
}

```

I tried differents ways but couldn't reach the result I want..
the result should be

```
[
    {
        id: "266",
        education_center: "Software House x",
        title: "Web Developer",
        start_date: "2021-01-26",
        end_date: "2022-01-26",
    },
    {
        id: "267",
        education_center: "Learning Academy xyz",
        title: "Teacher",
        start_date: "1998-11-26",
        end_date: "2021-01-22",
    },

]

```

Answer: 
```
const myObjects = {};
Object.keys(data).map((key) => {
    const splitKey = key.split('-');
    const elemId = splitKey[1];
    const realKey = splitKey[0];

    if (!myObjects[ elemId ]) {
        myObjects[ elemId ] = { id: elemId }; // Create entry
    }
    myObjects[ elemId ][ realKey ] = data[ key ]; 
});
// Turn into array
const myObjectsToArray = Object.values(myObjects);
// Or use the myObjects as a key/value store with ID as index
const selectedElement = myObjects[ myID ];

```
Here a slightly different solution, first getting all **unique** `id's`, then builiding the `result` array with looping over `Object.entries`.

```js
let data = { "education_center-266": "Software House x", "education_center-267": "Learning Academy xyz", "end_date-266": "2022-01-26", "end_date-267": "2021-01-22", "start_date-266": "2021-01-26", "start_date-267": "1998-11-26", "title-266": "Web Developer", "title-267": "Teacher", }

const ids= [...new Set(Object.keys(data).map((el)=>{
    return el.split('-')[1]
}))];

console.log(ids) //unique id's

let result = [];

ids.forEach((i)=>{
    let obj={id: i}
    Object.entries(data).forEach((el)=>{
        if(el[0].includes(i)) obj[el[0].split('-')[0]]=el[1];
    })
    result.push(obj)
})

console.log(result);
```
