javascript - 语法错误: Unexpected token >

Question

我正在尝试启动本地服务器，但出现了一大堆错误，有人可以告诉我发生了什么以及如何解决这个问题吗？

这是我尝试 node bot.js 时遇到的错误

C:\Users\Admin\Desktop\Client\src\Local Server>node bot.js
C:\Users\Admin\Desktop\Client\src\Local Server\bot.js:7

net.createServer(socket = > {
                      ^

net = require('net');

var clients = [];

const char = String.fromCharCode(0);

net.createServer(socket = > {


    socket.setNoDelay(true);

clients.push(socket);

console.log("Connected.");

socket.on('data', data = > {
    var x = data.readFloatBE(0);
var y = data.readFloatBE(4);
update(socket, x, y);
})
;

socket.on('error', error = > {}
)
;

socket.on('close', () = > {
    clients.splice(clients.indexOf(socket), 1);
console.log("Closed.");
})
;

socket.on('end', () = > {
    // ...
}
)
;

function update(sender, x, y) {
    for (var i = 0; i < clients.length; i++) {
        if (clients[i] !== sender) {
            clients[i].write(x + ":" + y + char);
        }
    }
}

}).
listen(8888, '127.0.0.1');


console.log("Listening at: 8888")
