Get course summary from Teachable

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"
