Extract a quote from YouTube transcripts

parseYouTubeTranscript.js

// Usage: Open the transcript view, select the line to start at, and call getQuoteFromVideo
// passing it just the number of lines to collect
// or
// Call getQuoteFromVideo passing it the number of lines to collect and an element id to start at
function getQuoteFromVideo(count, captionStartID){
   var captionLine = document.querySelector(captionStartID || '.caption-line-highlight');
   var text = '';

   for(var i = 0; i < count && captionLine; i++){
      text += captionLine.querySelector('.caption-line-text').textContent + ' ';
      captionLine = captionLine.nextSibling;
   }

   // Trim newlines and return text
   return text.replace(/\n/g, ' ');
}

// Start at a specific id
console.log(getQuoteFromVideo(20, '#cp-793'));

console.log('----');

// or start at the currently selected line
console.log(getQuoteFromVideo(20));

You don't design software. You don't you know what it is the user wants. In most cases the user
himself doesn't know what he wants. I mean, how many people ever worked in a software project
where you knew what the end result would be, and you turned out to be right... There's not a single
person I think that has ever had that happen to them. That means that designing things doesn't
actually work because if you design things and you don't know what you're designing for, the design
simply cannot work.
