Well then, so be it. It's a replacement for React's approach. It leverages web components and provides out-of-the-box data binding for it.
It supports the popular "angular style" syntax which is very easy to learn.
It is faster than React, easier to learn and since it is based on native components, it is more powerful as everything the browser has to offer - slim offers.
Unfortunately nobody cares for humility. PR is the only way to get responses. Sometimes you have to troll a little bit to get the right attention. Now would you like to discuss the library itself?
Ouch. Why do you think that, because of the syntax?
Well, your'e probably not getting to the point of using Slim.
It's not an angular replacement, It's competing with vue/react/backbone and such.
Why? Other than self righteous claims that it is better, there is no actual comparison. Add to that the return to object-oriented, internal-state-driven data management, the implicit magic, plus the indignation of the author, and we have at best a new Backbone. Which the community has moved on from.
You're right, I'm not getting the point, because you're not making one. You may have made a cool thing, but everyone will dismiss it if you immediately make claims of it's impending dominance.
