{@html}

Insert a string as HTML instead of as text.

<script>
  let note = '<strong>Saved</strong> just now'
</script>

<p>{@html note}</p>

{expr} always shows its value as text, so < stays <. {@html expr} parses the string and puts the resulting nodes in the page. When the expression changes, the old nodes are removed and the new ones inserted.

It does not sanitize

Whatever the string holds goes in as markup, scripts and event handlers included. Use {@html} only for content you wrote or already trust, such as the output of your own markdown renderer. Anything a stranger typed goes in with plain {expr}.
