How to give each element of an array of ojects a key

Question

If I have an array that looks like:

arr =[ { id: 'f794',label: 'Blue Bird' } ]

how do I give the element of it a key so I get

arr =["myKey":{ id: 'f794',label: 'Blue Bird' } ]

I have tried several different ways, like

arr[0]= '"myKey"' + ":" + arr[0]

which gives me

[ "myKey:[object Object]" ]

How do I get arr =["myKey":{ id: 'f794',label: 'Blue Bird' } ]

Thanks

You can do :

arr = arr.map((element) => {
   return ({"myKey" : element})
})

With perhaps a specific key for each element depending on what you want to do with it.
