+Reactive `Array.some`
+
+## Usage
+
+### Use with array of multiple refs
+
+```js
+import { useArraySome } from '@vueuse/core'
+const item1 = ref(0)
+const item2 = ref(2)
+const item3 = ref(4)
+const item4 = ref(6)
+const item5 = ref(8)
+const list = [item1, item2, item3, item4, item5]
+const result = useArraySome(list, i => i > 10)
+// result.value: false
+item1.value = 11
+// result.value: true
+```
+
+### Use with reactive array
