// 1. Go to a page like https://untappd.com/user/thesleepyvegan/beers?filter_type=type&filter_id=all&sort=
// 2. Open the Javascript console (Mac Chrome: Apple+Option+J)
// 3. Run the following Javascript snippet:
$('#style_picker option').map(function(i,e) { return $(e).text() }).splice(1).map(function(s) { var item = /([A-z/\(\) ]+) \((\d+)\)/.exec(s); return [item[1], parseInt(item[2])]; }).sort(function(a,b) { return b[1] - a[1]; });
// 4. Explore the resulting array and enjoy!


// Here are comments on what it does. Some browsers may require you to remove the comments for chaining
$('#style_picker option')                                  // select the beer text from the style picker dropdown
  .map(function(i,elem) { return $(elem).text() })         // take the text description of each
