I use Svelte full-time and absolutely love it, but I do have to admit I sometimes wonder what lead to the decision of {#if}{:else}{/if}, {#each}{/each}, etc syntax. Seems like there had to be less verbose, more consistent approach... But, I'm probably not fully-aware of the constraints and missing something.

I sometimes miss the brevity of the React way (which can also be good and bad) for handling conditional code-blocks {visible && <Component>} or {visible ? <Component1 /> : <Component2 />}
