I learn AI by
building things
I actually want to use.

var articles = fetchAllFeeds();

var articleDump = articles.map(function(a, i) {
  return '[' + (i+1) + '] SOURCE: ' + a.source +
    '\nTITLE: ' + a.title +
    '\nURL: ' + a.link +
    '\nSUMMARY: ' + a.desc;
}).join('\n\n---\n\n');

var top5Text = getTop5(apiKey, articleDump, dateStr);
var restText = getRestOfBriefing(apiKey, articleDump, dateStr);

var fullBriefing = 'TOP 5 TODAY\n\n' + top5Text + '\n\n' + restText;
var htmlBody = buildHtmlEmail(fullBriefing, dateStr);

GmailApp.sendEmail(RECIPIENT_EMAIL, subject, fullBriefing, {
  htmlBody: htmlBody,
  name: SENDER_NAME
});
