+- :gear: This rule is included in `"plugin:svelte/recommended"`.
+
+## :book: Rule Details
+
+The built-in `Date`, `Map`, `Set`, `URL` and `URLSearchParams` classes are often used in frontend code, however, their properties and methods are not reactive. Because of that, Svelte provides reactive versions of these 5 builtins as part of the "svelte/reactivity" package. This rule reports usage of the built-in versions in Svelte code.
+
+<!--eslint-skip-->
+
+```svelte
+<script>
+  /* eslint svelte/prefer-svelte-reactivity: "error" */
+
+  import {
+    SvelteDate,
+    SvelteMap,
+    SvelteSet,

+    SvelteURLSearchParams
+  } from 'svelte/reactivity';
