+## 模式匹配
+
+### 传统写法
+
+```javascript
+function processResponse(response) {
+  if (response.status === 200 && response.data) {
+    return { success: true, data: response.data };
+  } else if (response.status === 404) {
+    return { success: false, error: 'Not found' };
+  } else if (response.status >= 500) {
+    return { success: false, error: 'Server error' };
+  } else {
+    return { success: false, error: 'Unknown error' };
+  }
+}
+```
+
+### 模式匹配写法
+
+```javascript
+function processResponse(response) {
+  return match (response) {
+    when ({ status: 200, data }) -> ({ success: true, data })
+    when ({ status: 404 }) -> ({ success: false, error: 'Not found' })
+    when ({ status: status if status >= 500 }) -> ({ success: false, error: 'Server error' })
+    default -> ({ success: false, error: 'Unknown error' })
+  };
+}
+```
+
+### 数组长度分支也能优雅处理
+
+```javascript
+function handleArray(arr) {
+  return match (arr) {
+    when ([]) -> "Empty array"
+    when ([first]) -> `Only one element: ${first}`
+    when ([first, second]) -> `Two elements: ${first}, ${second}`
+    when ([first, ...rest]) -> `First element: ${first}, others: ${rest.length} items`
+  };
+}
+```
