<script setup lang="ts"

>

import {computed, ref, watch} from "vue"

;

const count = ref<number>(0

);

const countComputed = computed(() => { console.log("countComputed"); return count.value + 1

});

function countMethod() { console.log("countMethod"); return count.value - 1

; }

watch(count, () => { console.log("countWatch"

); })

const name = ref<string>("Max"

);

const nameComputed = computed(() => { console.log("nameComputed"); return name.value.toUpperCase

(); });

function nameMethod() { console.log("nameMethod"); return name.value.toLowerCase

(); }

watch(name, () => { console.log("nameWatch"

); })

</

script
