I tried to run my app on localhost using nodejs but i keep on getting this error : Uncaught SyntaxError: Unexpected token '<' .

This is my app.js code:

const http = require('http')
const fs = require('fs')
const port = 3000

const server = http.createServer(function(req,res){
    res.writeHead(200,{'Content-Type':'text/html'})
    fs.readFile('templates/index.html',null,function(error,data){
        if(error){
            res.writeHead(404)
            res.write('Error: File Not Found')
        } else {
            res.write(data)
        }
        res.end()
    })
})

server.listen(port,function(error){
    if(error){
    console.log('something went wrong', error)
    }else{
    console.log('server is listening on port ' + port)
    }
})

I tried looking into other threads that discussed this but I'm pretty new to this and I have no clue what they are talking about just following YouTube tutorials at the moment.
