Acknowledgements vs event emitting

[CGHill]

Hi,

I was curious about what was best practice in terms of using acknowledgments vs event emitting. Also what overheads there are for using acknowledgments. For example:

Client side:

function processResults(serverData){
    // Some (potentially large) amount of code for sorting through the servers data
}

socket.emit('get data', processResult);

Server side:

socket.on('load jobs', async (callback) => {
    const usersList = await dbFunctions.getUserList(companyID);

    callback(usersList);
});

vs.

Client side:

socket.on('get data response', (serverData) => {
    // Some (potentially large) amount of code for sorting through the servers data
});

socket.emit('get data');

Server side:

socket.on('load jobs', async () => {
    const usersList = await dbFunctions.getUserList(companyID);

    socket.emit('get data response', usersList);
});

So my question is: is there any issue with taking this approach?

I've been looking around and primarily only seen acknowledgments used to give simple responses back to the client rather than running more involved functions.
