const list = [item1, item2, item3, item4, item5]
const result = useArrayUnique(list)
// result.value: [0, 1, 2, 3]
item5.value = 1
// result.value: [0, 1, 2]

与反应式数组一起使用

const list = reactive([1, 2, 2, 3])
const result = useArrayUnique(list)
// result.value: [1, 2, 3]

list.push(1)
// result.value: [1, 2, 3]

与自定义函数一起使用

  { id: 1, name: 'baz' },
])

const result = useArrayUnique(list, (a, b) => a.id === b.id)
// result.value: [{ id: 1, name: 'foo' }, { id: 2, name: 'bar' }]
