Pattern matching trong Ruby là gì? Cách phân biệt case/in, toán tử in và =>?

15 tháng 2, 2026

Tóm tắt nhanh

Pattern matching (từ Ruby 3.0) kết hợp kiểm tra cấu trúc (matching) và trích xuất giá trị (destructuring) trong một bước. Khác với `case/when` chỉ so khớp giá trị bằng `===`, `case/in` kiểm tra "hình dáng" (shape) của dữ liệu và tự động gán biến một cách an toàn.
