+name: Delete directories
+---
+
+To recursively delete a directory and all its contents, use `rm` from `node:fs/promises`. This is like running `rm -rf` in JavaScript.
+
+```ts
+import { rm } from "node:fs/promises";
+
+// Delete a directory and all its contents
+await rm("path/to/directory", { recursive: true, force: true });
+```
+
+---
+
+These options configure the deletion behavior:
+
+- `recursive: true` - Delete subdirectories and their contents
+- `force: true` - Don't throw errors if the directory doesn't exist
+
+You can also use it without `force` to ensure the directory exists:
+
+```ts
+try {
+  await rm("path/to/directory", { recursive: true });
+} catch (error) {
+  if (error.code === "ENOENT") {
+    console.log("Directory doesn't exist");
+  } else {
+    throw error;
+  }
+}
+```

 Bun implements V8's heap snapshot API, which allows you to create snapshots of the heap at runtime. This helps debug memory leaks in your JavaScript/TypeScript application.
