JSON format is not recognized when I create an array with more than one element

Question

I want to create a JSON array which includes two elements. I wrote the following code:

  var myArray2 = [
      {
        "nome": "Aldo Maria",
        "indirizzo": "Viale Europa 1",
        "telefono": "3397889034"
      },
      {
        nome: "Maria13",
        indirizzo: "Viale Europa 1",
        telefono: "3397889034"
      }
    ];

I'm trying to parse it by using the Chrome extension Json Viewer Awesome but I get the error

Failed to parse invalid JSON format

On the other hand, I don't get this error while inserting a single element in the array, as in the snippet below:

{
    "myArray2": [
        {
            "message": "Welcome to Awesome JSON Viewer.",
            "status_code": 200
        }
    ]
}

Yes because your keys doesn't contains double quotes ("") for the part of json. The valid JSON would be

In JSON, keys must be strings, written with double quotes.

[{
        "nome": "Aldo Maria",
        "indirizzo": "Viale Europa 1",
        "telefono": "3397889034"
    },
    {
        "nome": " Maria13",
        "indirizzo": "Viale Europa 1",
        "telefono": "3397889034"
    }
]

In JavaScript, keys can be strings, numbers, or identifier names.See example

{ name:"John" }
