I would like to know how I could simplify this piece of code:

```
type PP struct {
    Profile_picture string `json:"profile_picture"`
}

json.NewEncoder(w).Encode(PP {result.Profile_picture})

```

Something like:

```
json.NewEncoder(w).Encode({result.Profile_picture})

```

^ this give me: `syntax error: missing operand`

And to get rid of:

```
type PP struct {
    Profile_picture string `json:"profile_picture"`
}

```

Thanks. Sorry for my english.
