Add current logged-in user to a new list item by using SharePoint 2013 Client Object Model

While working in SharePoint event registration with SharePoint-hosted app by using Client Side Object Model. In that code I had a requirement to add the current logged in user to list item. Here is the code to get the current logged-in user and add a new list item to the new list item.

var currentContext;
var web;
var user;

function init() {
//get current context
currentContext = SP.ClientContext.get_current();

//get current web details
web = currentContext.get_web();


function getCurrentUser() {
user = web.get_currentUser();
context.executeQueryAsync(onGetUserNameSuccess, onGetUserNameFailed);

function onGetUserNameSuccess() {
//custom code with current logged in user

function onGetUserNameFailed(sender, args) {
//log the error

function addNewItem()
// get the list for your item
var list = context.get_web().get_lists().getByTitle("ListName");

// create a ListItemCreationInformation object
var itemCreateInfo = new SP.ListItemCreationInformation();

// add this item to the list
var newItem = list.addItem(itemCreateInfo);

// Create a UserValue and set the LookupId to the current user
var userValue = new SP.FieldUserValue();
userValue.LookupId = user.get_id();

// Create a LookupValue and set the lookupId to the id of an event
var eventValue = new SP.FieldLookupValue();
eventValue.set_lookupId($("#Lookup Coloumn").val()); 

newItem.set_item('Title', user); //internal names
newItem.set_item('EventLookup', eventValue);

Function.createDelegate(this, this.onAddNewItemSucceeded),
Function.createDelegate(this, this.onAddNewItemFailed)

function onAddNewItemSucceeded() {
//custom code when Item Added Successfully
function onAddNewItemFailed(sender, args) {
//log the error
