When and how to reach for dump()
Any type
Pass strings, numbers, booleans, lists, maps, even controller objects — dump() walks them recursively.
Collapsible tree
Click any node to expand/collapse — perfect for inspecting deeply nested API responses and session payloads.
Dev only
Strip dump() calls before going to production — they expose internal state to every visitor.
