Udacity teaches Knockout as their front-end framework in their Front-End Nanodegree. I would guess it's because it's extremely simple to learn (no Babel or anything) yet also very powerful in teaching code organization concepts (such as ViewModel). It certainly isn't "modern," and doing anything remotely complicated will have you clawing at your eyes, but Udacity teaches it not as a framework to use, but as a framework to learn from. If I hadn't learned the basics of code organization by creating a simple app from Knockout, I'd be writing a _lot_ of logic in the render function of my React components (rather than computing them in a `mapStateToProps` selector), and I see a lot of beginner programmers do this. Not to say that React is _bad_ for a beginner to learn, but it makes it very easy to do things the wrong way without letting you know it's wrong. With Knockout, you literally _can't_ put any logic in the View layer without it looking ugly, which is a beautiful pattern for a beginner.
