How do i iterate through the json output in JS?

I have problems in iterating through the JSON output as the output is


{ "posts" : { "id":"152", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hell!" }
"posts" : { "id":"151", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hello!" }
"posts" : { "id":"147", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hey!" }
}

and i am not able to iterate in this JSON output!

 

Code:

var json = { "posts" : { "id":"152", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hell!" }
"posts" : { "id":"151", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hello!" }
"posts" : { "id":"147", "user":"Pankaj Patel", "to":"Pankaj Patel", "msg":"hey!" }
};

for(var i in json) {
	for(var j in json[i]) {
		// print
	}
}

 

please elaborate above method as the suggested way didn't work!!??
suppose I want to show output of

Code:

<li id="151">"Alice" to "Bob" : "hello!"</li>

then what would be the method!
