It's a myth that new languages and frameworks offer better productivity. Mostly it's just the flavor that's different, not the calories. Sometimes you get a genuine improvement, like react, but the vast majority of frameworks are completely optional when it comes to getting stuff done. I'm always reminded of this when I observe the Delphi team at work. Still lapping any web developer when it comes to shipping features.

Still thinking about moving to the fire monkey framework but no need to rush these things

Which might be fine if the system would work properly, as Ext would not directly compete with more "bare metal" component systems, but work as some kind of browser-based GUI DSL (which was what got a lot of people into it back in the days when DHTML was young).

Sadly, they seem more focused on introducing new features than fixing bugs or making all those elements work together (recent example: Conflict between new two-way binding and old statefulness of grid column sorting/order/filtering).

Mindshare isn't as good as with almost any other lib (some guy had the same problem you have with 6.2 with version 3.4, no solution ever posted), and due to it not being open source, there's not exactly a large community working on it, fixing things, adding new components etc.

And for all that, you have to pay a pretty stiff fee.

Which is the reason Marionette exists in the first place (well that and boilerplate code).

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.

I'm slowly coming round to the idea of committing to Angular for these reasons, just as HN commenters seem to be increasingly talking about React as the current Big Thing.

You are the Bruce Lee of Modern Javascript programming and I salute you.

A version optimized for being read out loud would make for a very satisfying guided meditation audio.

"Nothing. It's delegates all the way down."

How's my (de)motivational speaking?

Whoo, look at this guy with the "performance" and the hoola hoops and transistor radios.
