The examples are contrived & the comparison to React in the first place isn't in any way like-for-like (the first example is comparing ShadCN, an entirely different library, not just React).
React is a view state management library. Hyper is a DSL for a framework called Nue. They're not like-for-like tech. A better comparison would be something like Svelte which is a similar DSL (used with a framework called SvelteKit).
Fwiw JSX is also a minimal DSL used by React but if this article compared bare Hyper (without Nue) with bare JSX (without React), JSX would come out much much more minimal in the examples.
