I am new to Node.js and this is my first time using Node.js. When I tried to connect my index.html file I am getting this 'ReferenceError: html is not defined' error.
This is my index.js code

```
var http = require('http');
var fs = require('fs');
var port = 3030;
var host = '127.0.0.1';

fs.readFile('index.html', (err,html)=>{
    if(err){
        throw err;
    }
});

var server = http.createServer((req,res)=>{
    res.statusCode = 200;
    res.setHeader('Content-type','text/plain');
    res.write(html);
    res.end();
});

server.listen(port,host,() =>{
    console.log('Server started with port: '+port);
});

```

This is my index.html code,

```
`<html>
    <body>
        <h1>Node JS</h1>
    </body>
</html>

```

The error I got,

```
 res.write(html);          
           ^

ReferenceError: html is not defined

    at parserOnIncoming (_http_server.js:602:12)

```

If someone could tell Why I am getting this error, and am I missed anyting, that would be really great.
Thank You
