iswasmfast VS Uno Platform

At a glance, the bindings for wasm copy the data,

If the running code is short enough then that copy might easily make the wasm version much slower. That is indeed a known downside of wasm (calls to JS are somewhat slow, and copying of data even more so - wasm shines when you can avoid those things).

If it's not that, then a 10x difference suggests you are running into some kind of a VM bug or limitation.

WASM has its moments, as you can see in this[1] benchmark it outperforms JS and native addons on certain tasks.

Since the bottleneck with native addons is usually data copying/marshalling, and we have direct access to WebAssembly memory from the JavaScript side, using WebAssembly on this "shared" memory might become the best approach for computationally heavy tasks. I wrote about it a bit here[2].

A few years ago I did similar comparison but in context of Node.js and sans manual optimizations: https://github.com/zandaqo/iswasmfast

In my work, I have come to conclusion that it seldom pays off to go "native" when working with Node.js. More often than not, rewriting some computationally heavy code in C and sticking it as a native module yielded marginally better results when compared with properly optimized js code. Though, that doesn't negate other advantages of using said technologies: predictable performance from the start and re-using existing code base.

And Uno Platform (https://platform.uno/) is akin to React Native in terms of native controls usage.

also UNO Platform (C#) which is suitable for simple or complex cross platform business applications : https://platform.uno/

Why is this a problem? At face value, it isn't a problem. Taking a step back at a more global level, what does "uComponents" mean to the rest of the world? Many of the .NET developers who heavily use NuGet may have not even heard of Umbraco CMS, let alone a 3rd party plugin for it. What if people from the Uno Platform community are browsing NuGet for some kind of components extension library? You can see, this could get confusing outside the scope of the Umbraco community/ecosystem. On top of this, uComponents was developed against Umbraco v4, with its last release in 2016, now it's there to be lingering on the NuGet repository until the end of time, set in stone.

Not a fan of XAML after trying to get into it, but there is Uno Platform. It wraps native widgets on mobile, just like React Native (which is good for accessibility), and uses C#. https://platform.uno/

My guess is that it's mainly focused on mobile. On Windows, it has no overhead (behaving like a normal WinUI 3 app), on macOS I think it uses Catalyst by default (which was developed by Apple to make more iOS apps available for Mac desktops) and on Linux it draws its own widgets that the devs try imitating the GTK style with.

On Android and iOS, it just uses the native widgets which I think is a better experience so you can see my reasons for guessing it's mobile-first. That may or may not be what you want.

> ...building UIs with the document/element api

When the whole premise is flawed, JSX or not, does it really matter if there is a better or worse way of misusing a technology not meant for UIs?

Leave HTML and JavaScript to Wikipedia and other hypertext document libraries.

Unfortunately, WASM is not there yet, but people are trying: https://platform.uno.

Also, .NET 7 brought a lot of stability so I am confident you'll have a better experience. I hope to hear back from you. It would be great to have any feedback at our repo - https://github.com/unoplatform/uno/discussions
