How can you include a comma between two objects within a string, excluding the last object, using JavaScript?

I have a string object stored in a variable passed from another class. My question is how can I add a comma between two objects, excluding the last object? Below is my code snippet:

{
        "id":"57e4d12e53a5a",
        "body":"asdas",
        "published":"Fri, 
        23 Sep 2016 06:52:30 +0000",
        "type":"chat-message",
        "actor":
            {
            "displayName":"beau",
            "objectType":"person",
            "image":
                {
                "url":"http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50?s=80&d=mm&r=g",
                "width":48,"height":48
                }
            }
    },
    {
        "id":"57e4d51165d97",
        "body":"jackiechanSADAS",
        "published":"Fri, 23 Sep 2016 07:09:05 +0000",
        "type":"chat-message",
        "actor":
            {
                "displayName":"beau",
                "objectType":"person",
                "image":
                    {
                        "url":"http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50?s=80&d=mm&r=g",
                        "width":48,
                        "height":48
                    }
            }
    },
    {
        "id":"asas",
        "body":"peterting",
        "published":"Fri, 23 Sep 2016 07:09:05 +0000",
        "type":"chat-message",
        "actor":
            {
                "displayName":"beau",
                "objectType":"person",
                "image":
                    {
                        "url":"http://www.gravatar.com/avatar/205e460b479e2e5b48aec07710c08d50?s=80&d=mm&r=g",
                        "width":48,
                        "height":48
                    }
            }
    }

My challenge is how to programmatically add a comma "," between each object, excluding the last one. Since the entire content is stored as a string, I need the comma for proper parsing into an object.

To resolve this, you can implement Regex:

JSON.parse('[' + string.replace(/}\s*{/g, '},{') + ']');
