riffle.js is a little nicer and more transparent than bacon.js

RiffleWatchClicks.js

// call this separately to load the lib...
$.getScript('https://rawgithub.com/flowgrammer/Riffle/master/riffle.js').then(function () {
  var clicks = stream(function (outFn, selector) {
      $(selector).on('click', function (ev) {
        outFn($(this));
      });
    })
    , hrefs = stream(function (outFn, $element) {
      outFn($element.attr('href'));
    })
    ;
    
  hrefs.input(clicks);
  
  clicks.invoke('[data-focus-id] > a');
  hrefs.onOutput(function (href) {
    console.log(href);
  });
});
