@ There is a clear ABSOLUTE difference tho. With Svelte, it was too magical at the point even svelte recognized it and made special markers on the code for it. In the react's case it is just doing optimizations under the hood, neither the semantics nor the syntax of the code is changed on that compiler magic. But I see how things are, haters gonna hate.

 @MrMudbill Which you don't know a priori, so this comment is pointless.

Immediate mode UIs are generally extremely simple in terms of layouting and style, this is the part of the picture you are missing. Rendering the DOM is slow because: (1) We use JS to do it (2) It is retained mode, so all the changes are cached and rendered the minimum as possible (3) The layouting and styling system of modern HTML + CSS is [extremely complex], it allows you to do a huge amount of positioning, calculations, transformations, event based styles, very compound and complicated responsive layouts, animations, etc... all of those things take time, and they are pretty slow to work It is a different beast altogether.

@SilvestreVivo You should think "how much money is react making them" instead of "how much money is react costing", people usually don't just use technologies that don't benefit them in some way.

Angular is still slow as heck, and react is still a little better (with the compiler, WAY better, angular is still stuck with the old change detection mechanisms for most of its ecosystem currently). Most JS frameworks are trash at speed, with few exceptions like svelte or solid-js.
