Get course summary from Teachable

script.js

var result = $('.section-item .item').get().reduce(function(total, item) { 
  var text = $(item).text().split("\n").join(" "); 
  var matches = /.+\((\d):(\d\d)\)/g.exec(text); 
  
  var minutes = parseInt(matches[1]); 
  var seconds = parseInt(matches[2]); 
  
  var totalMin = total[0] + minutes; 
  var totalSec = total[1] + seconds; 
  
  if (totalSec > 60) { 
    totalMin += 1; 
    totalSec -= 60; 
  } 
  
  return [totalMin, totalSec] 
}, [0,0]);

console.log($('.section-item .item').size() + " micro videos, " + result[0] + " minutes, " + result[1] + " seconds");

I needed a way to quickly count the number of videos and the total course duration for courses on Teachable. There's no obvious way to find this info in the UI, so I wrote a very hacky JS script to calculate it.

Instructions:

1. Go to the page for the course (e.g., https://training.gruntwork.io/p/terraform)
2. Open the web dev console
3. Paste the script above and hit enter
4. You should get output like: "30 micro videos, 92 minutes, 53 seconds"
