I know you're probably asking it only rhetorically, but it's the way to mark something as reactive for the Svelte "compiler", cleverly using the existing JS label syntax.[1]

"cleverly"

It is clever. It’s just a named label with the name “$”. It’s perfectly standard JavaScript, and it’s super easy to remember.

I like how jquery used $ to namespace all methods and now svelte does not repeat, but rhymes.
