Enhancing Google Apps Script with Object Literals for Document Styling

// Define styles using object literals
const styles = {
  title: {
    [DocumentApp.Attribute.FONT_SIZE]: 24,
    [DocumentApp.Attribute.BOLD]: true,
    [DocumentApp.Attribute.FOREGROUND_COLOR]: '#0000FF' // Blue color
  },
  subtitle: {
    [DocumentApp.Attribute.FONT_SIZE]: 18,
    [DocumentApp.Attribute.ITALIC]: true,
    [DocumentApp.Attribute.FOREGROUND_COLOR]: '#FF0000' // Red color
  },
  normalText: {
    [DocumentApp.Attribute.FONT_SIZE]: 12,
    [DocumentApp.Attribute.BOLD]: false,
    [DocumentApp.Attribute.FOREGROUND_COLOR]: '#000000' // Black color
  }
};

function styleDocument() {
  // Open a document by ID or create a new one
  const doc = DocumentApp.openById('YOUR_DOCUMENT_ID');
  const body = doc.getBody();
  
  // Apply styles to the title
  const title = body.appendParagraph('This is the Title');
  title.setAttributes(styles.title);
  
  // Apply styles to the subtitle
  const subtitle = body.appendParagraph('This is the Subtitle');
  subtitle.setAttributes(styles.subtitle);
  
  // Apply styles to normal text
  const normalText = body.appendParagraph('This is some normal text.');
  normalText.setAttributes(styles.normalText);
  
  // Save and close the document
  doc.saveAndClose();
