+# useArrayReduce
+
+Reactive `Array.reduce`.
+
+## Usage
+
+```ts
+import { useArrayReduce } from '@vueuse/core';
+
+const sum = useArrayReduce([ref(1), ref(2), ref(3)], (sum, val) => sum + val);
+// sum.value: 6
+```
+
+### Use with reactive array
+
+```ts
+import { useArrayReduce } from '@vueuse/core';
+
+const list = reactive([1, 2]);
+const sum = useArrayReduce(list, (sum, val) => sum + val);
+
+list.push(3);
+// sum.value: 6
+```
+
+### Use with initialValue
+
+```ts
+import { useArrayReduce } from '@vueuse/core';
+
+const list = reactive([{ num: 1 }, { num: 2 }]);
+const sum = useArrayReduce(list, (sum, val) => sum + val.num, 0);
+// sum.value: 3
+```
+
+## Type Declarations
+
+```ts
+export type UseArrayReducer<PV, CV, R> = (
+  previousValue: PV,
+  currentValue: CV,
+  currentIndex: number,
+) => R;
+export type UseArrayReduceReturn<T = any> = ComputedRef<T>;
