Outlook with TypeScript SSO

You can use the Yeoman Generator to create an Outlook Add-in project using VS Code with TypeScript
The link above displays these three files:

package.json 
manifest.xml 
webpack.config.json 

This page displays all the other files in this project:

function writeDataToOutlook(result) { 
  let data = []; 
  let userProfileInfo = filterUserProfileInfo(result); 

  for (let i = 0; i < userProfileInfo.length; i++) { 
    if (userProfileInfo[i] !== null) { 
      data.push(userProfileInfo[i]); 
    } 
  } 

  let userInfo = ""; 
  for (let i = 0; i < data.length; i++) { 
    userInfo += data[i] + "\n"; 
  } 

  Office.context.mailbox.item.body.setSelectedDataAsync(userInfo, { coercionType: Office.CoercionType.Html }); 
}
