[SOLVED] Append data to localStorage failing

Append data to localStorage failing

I am trying to push data to local storage. What I have is basically what others but does not seem to work.

var data = {"fullname":data['name'],"picture":"<img src="+data['picture']+" />"}
var result = JSON.parse(localStorage.getItem("oauth2-test-params"));
result.push(data)

My object looks like this console.log(localStorage):

{
"picture": "two",
"fullname": "Junk",
"test-params": "{\"three\":\"77-96L2N\",\"four\":\"junk\",\"five\":\"Bearer\",\"expires_in\":\"3599\"}"
}

What I am looking to do is

{
"test-params": "{
 "fullname":"Junk",
 "picture": "two",
 "three":"77-96L2N",
 "four":"junk","five":"Bearer",
 "expires_in":"3599"}"
}

I want to add picture and fullname to the test-params object not outside of. The code I have isn't working and it is what everyone else is using.
I keep getting this error result.push is not a function

Solution

Replace

result.push(data)

with

Object.assign(result, data)
