 UCE is server-first C++ with a small template preprocessor. It does not try to be React, but several concepts map cleanly.

 The function library includes small collection helpers for common route/menu/card transformations:
 
 ```cpp
-auto visible = filter(routes, [](String route) { return(route != "admin"); });
-auto labels = map(visible, [](String route) { return(to_upper(route)); });
-DValue app_items = dv_filter(menu, [](DValue item, String key) { return(item["section"].to_string() == "app"); });
-DValue by_section = dv_group_by(menu, [](DValue item, String key) { return(item["section"].to_string()); });
+auto visible = routes.filter([](String route) { return(route != "admin"); });
+auto labels = visible.map([](String route) { return(to_upper(route)); });
+DValue app_items = menu.filter([](DValue item, String key) { return(item["section"].to_string() == "app"); });
+DValue labels_by_key = menu.map([](DValue item, String key) { DValue out; out = item["label"].to_string(); return(out); });
 ```
 
 Use these when a short transformation is clearer than a loop. Prefer explicit loops for side effects or multi-step validation.
