If you go to youtube.com and open up the Subscriptions column and click different channels, the page will change dynamically. However, weirdly enough, there's no way for a JS script to know:
- If the page has changed
- When the page has finished changing/loading
Just do this experiment:
- Go to chrome dev console and type
let body=document.body; - Click to a different channel.
- Type in dev console
body===document.body;
And the result will be true
I'm honestly very confused about what's going on and what I can do to go around this.
