Google Apps Script allows you to create apps that integrate with Google Workspace.
You write code in modern-ish JavaScript (most ES6 features supported) and have access to built-in libraries for applications like Gmail, Calendar, Drive, and more.
There's nothing to install—the code editor is in the browser, and scripts are saved to Google Drive and run on Google's servers (V8 runtime).

Getting Started

function onOpen() {
  var ui = SpreadsheetApp.getUi();
  ui.createMenu('My Custom Item')
	.addItem('Menu 1', 'callbackFunction1')
    .addItem('Menu 2', 'callbackFunction2')
    .addSeparator()
    .addItem('Menu 3', 'callbackFunction3')
    .addToUi()
}

Code Example: Creating a custom menu

// Code.gs
let template = HtmlService.createTemplateFromFile('Email-Invitation')
template.data = {workshops: data}
let html = template.evaluate().getContent()
let draft = GmailApp.createDraft(
  '', 
  `Frontend Masters Workshops`, 
  '', 
  {htmlBody: html}
);

Implementation & UI

// "Printing scriptlets" <?= ?> in HTML Templates
<? for(var i = 0; i < data.workshops.length; i++){ ?>
  <p><?= data.workshops[i].workshopName ?><p>                           
<? } ?>
