Very clickbaity title, this is definitely not "just Javascript you already know": <script> import counts from './store.ts'; import {onMount} from 'svelte'; </script> <button on:click={() => $counts.a += 1}> Increment A ({$counts.a}) </button> In that tiny snippet there's so many non-js things, like "where did that onMount go?", "why does $counts come from? is it from 'count'?", "how do events work?", "does the onclick update the value later on?", "can I do $counts.a++ instead? once? twice?" etc.
