knockout VS Prism

The approach is not new, essentially a variation of Knockout, Alpine, and similar "JS-in-HTML" approaches.

SolidJS and Tauri form another potent combination for creating performant, lightweight, and secure experiences. SolidJS is a reactive UI library that is similar to Svelte in the way it compiles away reactivity and updates the DOM directly, but it also incorporates a fine-grained reactivity system reminiscent of libraries like Marko, Knockout, and MobX.

People act like Signals are a new discovery. KnockoutJS was using them 13 years ago and other libraries used them before that.

Knockout JS is a Javascript library which uses the MVVM pattern to bind data to certain DOM elements. Within Magento, we usually define a View-Model (which is a .js file) and a Template (which is a .html file), and the data in the template file is bound to the view-model, meaning whenever the data in the view-model changes, the template file changes too.

I still use Knockout[0] for almost an identical experience.

One of the first uses of this concept was in knockout, which used the same function with and without arguments for write/read access.

To do this, use a Javascript library called knockout.js

You could use a JavaScript framework called KnockoutJS which uses the MVVM pattern.

Magento is built with PHP. A good understanding of PHP is generally enough to perform different development tasks such as building modules. However, developers often need to work with libraries like Knockout.js and Less when developing themes.

It looks to me like you're trying to avoid setting a property if the value won't change, and you want to know if it did change. Here's an alternate approach which you could take https://github.com/PrismLibrary/Prism/blob/master/src/Prism.Core/Mvvm/BindableBase.cs

See https://github.com/PrismLibrary/Prism/blob/master/src/Wpf/Prism.Wpf/Mvvm/ViewModelLocator.cs

The Prism Library has a base class you can implement called BindableBase for this exact purpose of not copying and pasting the same code over and over again.
