Why do we need external.matchmedia.js for?


I'm working on the interactive website videos, and I realized I need the matchmedia.js file. I added to my mock website, but I'm wondering why do I need it for? I tried to read it, but I'm afraid I don't understand what it does. Also, is it something I could use in my personal website?

Thank you for the response! And thank you for the tutorials, I find them extremely helpful!
