Reuse variable in socket io functions

So now I'm storing info when user submits login form. 

io.on('connection', (socket) => {

let userInfo; 

    socket.on('login', (data) => {
        userInfo = data;
        console.log(userInfo); // {username: 'testusername'}
    });

    socket.on('lobby-left', (userInfo) => {
        console.log(userInfo); // { } 
    });

The problem is that in lobby-left I don't get any info from the variable anymore. I get empty brackets { }. How can I reuse the variable so I can use the login info in all functions ?

You need assign it to userInfo

let userInfo; 

socket.on('login', (data) => {
    userInfo = data;
    console.log(userInfo); // {username: 'testusername'}
});

socket.on('lobby-left', (userInfoParam) => {
    console.log(userInfo); // { } 
});
