What is the difference between these two ways of getting the same thing (a new menu item)?

Version 1

 function onOpen(e) {
       .createMenu('My Menu')
       .addItem('My Menu Item', 'myFunction')
       .addSubMenu(SpreadsheetApp.getUi().createMenu('My Submenu')
           .addItem('One Submenu Item', 'mySecondFunction')
           .addItem('Another Submenu Item', 'myThirdFunction'))

Version 2

function onOpen() {
  var menu = [{name: "My Menu Item", functionName: "myFunction"}]
  SpreadsheetApp.getActiveSpreadsheet().addMenu("My Menu", menu);

This is a method of Spreadsheet class, i.e., it only applies to spreadsheets. All it does is add a new menu item with second-level submenus. On the upside, the syntax is very simple.


This method is currently available for three apps: SpreadsheetApp, DocumentApp, and FormApp. It returns an instance of user interface which can be used for more than just adding a menu item. One can show alerts, prompts, dialogs, and even add an interactive sidebar with custom content. Also, the menu creating options are richer: they allow separators and nested submenus. There are special add-on menus, too. Accordingly, the syntax is more verbose.


Neither of two methods is deprecated; use whichever fits your goal better.


Another difference: you cannot add submenus (child menu items under parent menu items) with addMenu. This limitation pretty much self-deprecates the addMenu method despite the cool syntax.

    This answer should be edited to clarify the "difference" from @user79865's answer You state "you cannot add submenus" yet the other answer indicates that you can add a "new menu item" (parent) with "second-level submenus" seems like a contradiction or one or both of the answers are unclear.
