I have an string from backend source, of format:

numbers: "1123763449056714753, 1123764853364097024, 1123770213739241473..."

I want to convert it into key-value pair something form so that I can map over these ids for my individual item div:

```
["numbers": [ 
              {"id":1123763449056714753 }, 
              {"id":1123764853364097024 },
              {"id":1123770213739241473 },
             ....
            ]
]

```

or

```
[                 {"id":1123763449056714753 }, 
                  {"id":1123764853364097024 },
                  {"id":1123770213739241473 },
                 ....

    ]

```

I tried using forEach()/ map() but gets error as undefined. Also I am not sure whether it is a collection of string or array of strings
Please help
