vue 基础

声明式渲染

类似C#里的 $'' 字符串插值

<body>
    <div id="counter">
        Counter: {{ counter }}
    </div>
    <script>
        const Counter = {
            //
            data() {
                return {
                    counter: 0
                }
            },
            //
            mounted() {
                setInterval(() => {
                    this.counter++
                }, 1000)
            }
        }
        //console.log(typeof Counter.data().counter)
        Vue.createApp(Counter).mount('#counter')
    </script>
</body>
</html>

此变量是响应式的
