Please fix the problem of this code:

const getJSONString = function(obj)

{

return JSON.stringify(obj, null, 2);

}

const port = 3000,

http = require("http"),

httpStatus = require("http-status-codes"),

app = http.createServer();

app.on("request", (req, res) =>

{

if(req.url=="/form.html") //DISPLAY FORM

{

var output=

`

form{color:navy;}

table{border:5px solid navy;background-color:yellow;}

th{color:yellow;background-color:navy;border:solid navy 2px;outline:solid navy 2px;border-}

input[type='text']{background-color:#DEDEE6;border:4px solid navy;}

input[type='button'],input[type='reset']{color:white;background-color:black;border:1px solid white;}

label{color:navy;font-weight: bold;}
