> let's kick things off with jsx.

Of all the problems I have with React, and I do have a few, JSX is not one of them.

If you are going to be using a language to generate HTML, you are either going with a component approach that wraps HTML in some object library that then spits out HTML, or you are stuck with a templating language of some sort. (Or string concatenation, but I refuse to consider that a valid choice for non-trivial use cases.)

JSX is a minimal templating language on top of HTML. Do I think effects are weird and am I very annoyed at how they are declaration order dependent? Yup. But the lifecycle stuff is not that weird, or at least the latest revision of it isn't (earlier editions... eh...). The idea of triggering an action when a page is done loading has been around for a very long time, and that maps rather well to JSX's lifecycle events.

> React alone provides little to nothing

Throw in a routing library, and you are pretty much done.

Now another issue I do have is that people think React optimizes things that it in fact does not, so components end up being re-rendered again and again. Throw Redux in there and it is easy to have 100ms latency per key press. Super easy to do, and avoiding that pitfall involves understanding quite a few topics, which is unfortunate. The default path shouldn't lead to bad performance.

> The concept of components and the idiotic life cycles

Page loads, network request is made. Before React people had listeners on DOM and Window events instead, no different.

Components are nice if kept short and sweet. "This bit of HTML shows an image and its description" is useful.

No, I've worked on embedded systems, I realize how much of a gigantic waste everything web is. But making tight and small React apps is perfectly possible.

And yes, if you pull in a giant UI component library things will balloon in size. It is a common beginner mistake, I made it myself when I first started out. Then I realized it is easier for me to just write whatever small set of components I need myself, and I dropped 60% of my bundle app size.

In comparison, doing shit on the backend involves:

1. Writing logic in one language that will generate HTML and Javascript
2. Debugging the HTML and Javascript generated in #1.

And then someone goes "hey you know what's a great idea? Let's put state on the back end again! And we'll wrap it up behind a bunch of abstractions so engineers can pretend it actually isn't on the back end!"

History repeats itself and all that.

SPAs exist for a reason. They are easier to develop and easier to think about. And like it or not, even trivial client side functionality, such as a date picker, requires Javascript (see: https://caniuse.com/input-datetime).

SPAs, once loaded, can be very fast and scaling the backend for an SPA is a much easier engineering task (not trivial, but easier than per user state).

Is all of web dev a dumpster fire? Of course it is. A 16 year old with VB6 back in 1999 was 10x more productive than the world's most amazing web front end developer now days. Give said 16yr old a copy of Access and they could replace 90% of modern day internally developed CRUD apps at a fraction of the cost. (Except mobile support and all that...)

But React isn't the source of the problem, or even a particularly bad bit of code.
