众所周知，vue2有生命周期，而vue3也有
而vue2的created和beforecreated在vue3中都由setup替代了<script setup lang="ts">
import { onBeforeMount, onMounted, onBeforeUpdate, onUpdated,onBeforeUnmount,onUnmounted } from 'vue'
console.log('创建生命周期')
onBeforeMount(() => {
console.log('挂载前')
})
onMounted(() => {
console.log('挂载完毕')
})
onBeforeUpdate(() => {
console.log('更新前')
})
onUpdated(() => {
console.log('更新完毕')
})
onBeforeUnmount(() => {
console.log('卸载前')
})
onUnmounted(() => {
console.log('卸载完毕')
})
</script>
