Handle click event inside {#each} block in svelte

Question

I am a svelte beginner and i have a problem with event handlers inside the each block. In the Repl when i click shuffle multiple times, i have multiple event listener for the heart inside the card. The click event on the card works fine and has only one event listener. How can i prevent to have multiple event listeners on the heart?

You could remove they key, that way the items are re-created, and the event handlers aren't sticking around.

{#each dataShow as d (d.poi)} => {#each dataShow as d}
