响应式地获取数组的总和。

用法

import { useSum } from '@vueuse/math'

const array = ref([1, 2, 3, 4])
const sum = useSum(array) // Ref<10>

import { useSum } from '@vueuse/math'

const a = ref(1)
const b = ref(3)

const sum = useSum(a, b, 2) // Ref<6>

类型声明

export declare function useSum(
  array: MaybeRefOrGetter<MaybeRefOrGetter<number>[]>,
): ComputedRef<number>
export declare function useSum(
  ...args: MaybeRefOrGetter<number>[]
): ComputedRef<number>
