> Instead, Svelte runs at build time, converting your components into highly efficient imperative code that surgically updates the DOM.

So, Svelte is compiled into web assembly? If not, given the emitted imperative code is less efficient than emitted web assembly and the emitted imperative code is less concise than the original declarative code, then what would be the advantage of an imperative translation of the declarative Javascript code compared to emitted web assembly or the original?
