项目报错：Assignment to constant variable.

<script setup>
import { ref, computed, reactive } from 'vue';

defineProps({
	msg: String
});

const count = ref(0);
const count1 = reactive(1);
console.log(count, 'count');

const computedValue = computed(() => {
	return count1++;
});
console.log(computedValue, 'computedValue');
</script>

const一般是声明常量，如const a=1,const声明的变量不得改变值，这意味着，const一旦声明变量，就必须立即初始化，不能留到以后赋值。

原因：const问题报错 常量不可修改其值

const computedValue = computed(() => {
return count1 > 0 ? ‘2’ : ‘3’;
});
