Convert array values to objects

Question

I have this code

const jsonArray = [1,2,3,4,5];

I want to convert it so I can get

{
 "id" : 1
},
{
 "id" : 2
},
{
 "id" : 3
},
{
 "id" : 4
},
{
 "id" : 5
}

So I need to add "id" key for all the objects outputs

@Jacquesジャック Doesn't work, you're not returning anything from the block — Roberto Zvjerković, Apr 23 '21 at 09:43
@RobertoZvjerković You're right, since it's returning an object I cannot use the shorthand return. My mistake. `const myObj = jsonArray.map((val) => { return {id: val}});` — Jacques ジャック, Apr 23 '21 at 09:49
@Jacquesジャック You can, you just have to wrap the object in parens like this: `(val) => ({ id: val })` — Roberto Zvjerković, Apr 23 '21 at 09:49
@RobertoZvjerković You're correct, but I hate that syntax as it's easy to think they're just double wrapped in curlys. — Jacques ジャック, Apr 23 '21 at 09:51

Try the map function

jsonObjectArray = jsonArray.map((ele) => {return {"id": ele}})

You can use map.

jsonArray.map(id=>({id}))

You could use Array.prototype.map() for that:

const jsonArray = [1,2,3,4,5];
        
const arrayofObjects = jsonArray.map(e => ({id: e}))

console.log(arrayofObjects);
