I believe Trello uses Knockout.js

And at least before Atlassian bought it (I haven't used since then), it was a responsive and plasant piece of software.

The Crew Displays do not use Knockout.js. As far as I am aware this is possibly used in some other asset management software developed in-house for manufacturing teams but definitely not onboard Dragon.

I'm sitting over here believing Knockout.js was better than today's JS systems.
