There is an error in client.js, but I don't know where to fix it.
It seems to be an error with the symbol <, but I don't use it anywhere, so it's refreshing.
If you are familiar with javascript, please let me know
Error Contents
SyntaxError: expected expression, got'<'client.js:1

I created it by referring to the site, but I don't know how to solve it
Source code for the project created using the above URL
client.js
$(function(){
var socket = newio.Socket(null, {port:8080});
socket.connect();
function iosHandleOrientation(event){
variableData=event.accelerationIncludingGravity;
socket.send(orientData.x+"+orientData.y+"+orientData.z);
}
window.addEventListener("devicemotion",iosHandleOrientation, true);
socket.on('message', function(obj){
data=obj.split("";
$('#data') .append("<tr><td>"+parseFloat(data[0]).toFixed(3)+"</td><td>"+parseFloat(data[1]).toFixed(3)+"<td>td>2Float;"
});
});
server.js
varfs=require('fs');
var http=require('http'),
io= require ('socket.io'),
server = http.createServer(function(req,res){
fs.readFile('./socket.html', 'utf-8', doRead);
function doReard(err,data){
res.writeHead(200, {'Content-Type':'text/html'});
res.write(data);
res.end();
}
});
server.listen (8080);
var socket =io.listen(server);
socket.on('connection', function(client){
client.on('message', function(message){
client.broadcast(message);
console.log(message);
});
client.on('disconnect', function(){
console.log('Connection closed.');
});
});
socket.html
<!DOCTYPE html>
<html lang="ja">
<metacharset="utf-8">
<head>
<script type="text/javascript" src="https://cdn.socket.io/socket.io- 1.4.5.js">/script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js">/script>
<script src="client.js"></script>
</head>
<body>
<table id="data">
<tr>th>x>/th>y>/th>th>z>/th>>
</table>
</body>
</html>
This may be because server.js returns socket.html regardless of the path of the request.
The browser looks at the tag <script src="client.js">/script> and requests to the server, but I think the error occurred because it was returned by html.
Use Express for ease of routing.
