Will this actually generate different code then the below in dart2js?

+      for (int i = 0; i < a.length; i++) {
+        a[i] = i;
+      }
+
+      expect(a.filter((x) => x >= 1000).length, equals(24));
+  });
+
+  test('filter_typed', () {
+      Float32Array a = new Float32Array(1024);
+      for (int i = 0; i < a.length; i++) {
+        a[i] = i;
+      }
+
+      expect(a.filter((x) => x >= 1000).length, equals(24));
+  });
+}
