KnockoutJS is far from dead, and it’s actually still being improved and evolved (see Technical Knockout) but newer frameworks seem a far better bet for our needs, considering activity and performance.
Why is knockout JS so little popular?
It is strange why knockout.js is so little popular, it's hugely underrated in my opinion. Vue.js is not better than knockout for example. They stick binding to their own class, which makes extension of viewmodel classes difficult, while in knockout any Javascript class can be bound.
Do I need node tools to use knockout?

What is the difference between knockout and ReactJS?
In comparison, Knockout introduces the notion of data-binding where specific dom elements are bound to observable data, such that that data change only effects specific parts of a dom. No diff required. In react, it's standard practice to write code in JSX format which requires a transpiler to convert the JSX into a standard javascript form.

What is the key value of knockout?
What i do think is the key value of Knockout lies in that I strongly feel separation of concerns (SoC) - and MVVM (with all it's flaws) as a paradigm to implement this- is still the cleanest and easiest to maintain way to program Enterprise applications. And Knockout still is the best library (well, I haven't checked them all) to adhere to this paradigm.
Is TKO in Alpha 3?
Incidentally, somewhat related — TKO is in Alpha-3 now. I'd be interested in feedback on it in general, particularly as a drop-in replacement (i.e. backwards compat.) with ko 3.4 in large-scale apps. Thanks in advance.
Can you use Knockout with webpack?
You can't use knockout with webpack now, webpack disrespects any global variables and knockout still sets the ko variable to window object. The knockout-validation project just breaks when using with webpack (the issue is in "use strict" statement which webpack preceedes to all its modules, and rightly so, but it completely breaks knockout-validation; I wanted to file and issue there, but the library seems to be completely abandoned by now). Any modules that extend knockout have to extend the global ko object in window. Webpack goes against this approach as well. These are just three resent issues I've resently put up with, I'm sure there're more.
Is knockout a realistic option?
If Knockout (or some extension of it) did that well, it would be a realistic option for web development again.

The important point is that Knockout still is a very relevant, very elegant and easy-to-use technological solution.

Another reason to opt away from React is the way that it can affect the market for rendering engines... Blink/WebKit have taken over in such a way that competition in this space is exceedingly is sparse and difficult.

Does TKO JSX do diff?
TKO-jsx also does a diff-DOM-compare when an observable array of JSX nodes is updated i.e. even without binding foreach - the following will do a least-diff update: <div>{observableArray}</div>. Where observableArray is an array of (possibly heterogeneous) "JSX", text, Promise, or observable values. Copy link.

Should I write a blog about knockout?
I think you should write a blog about your experience going from Knockout to React. That would be very informative to the overall community and if you do find something that is deficient (read: not merely different) maybe it would inspire some improvements. Competition is good! Convincing everyone to just convert to React is not in the spirit of competition. Besides, like I said, React and Knockout just approach the problem in very different ways (virtual dom vs. data binding), which is why a conversion tool is probably not possible. If you do decide to write something up, I'd definitely like to hear the specific justifications for the move; IE: there is something you just can't do in Knockout that only React can solve. That would be quite interesting! Also something to discuss on the knockout google groups since you might get more eyes on that.
