先上Vue3组件的实例代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>

</head>
<body>
    <div id="michael">
        <michael></michael>
        <sky></sky>
        <blue></blue>
    </div>
    <script>
       var app= Vue.createApp({
            data(){
                return {
                    "msg":"hello"
                }
            }

        });
        app.component('michael', {
            'template':`
                <div>michael</div>
            `
        });
        app.component('sky', {
            'template':`
                <div>sky</div>
            `
        });
        app.component('blue', {
            'template':`
                <div>blue</div>
            `
        });
        app.mount("#michael");
    </script>
</body>
</html>

注意：以上是Vue3的叠加的写法，不一定要写成链式的代码。

运行效果：

动态组件的写法:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
    <style>
        .abc{
            width: 100px;
            height: 100px;
            border: 1px solid black;
            background-color: green;
            color:white;
            
        }
    </style>

</head>
<body>
    <div id="michael">
        <!--<michael></michael>
        <sky></sky>
        <blue></blue>-->
        <button v-for='tab in btnMsg' :key="tab" @click="tabName=tab">
            {{tab}}
        </button>
        <component :is="tabName" class="abc"></component><!--动态组件-->
    </div>
    <script>
       var app= Vue.createApp({
            data(){
                return {
                    "msg":"hello",
                    "btnMsg":["michael","sky","blue"],
                    "tabName":"michael"
                }
            }

        });
        app.component('michael', {
            'template':`
                <div>michael</div>
            `
        });
        app.component('sky', {
            'template':`
                <div>sky</div>
            `
        });
        app.component('blue', {
            'template':`
                <div>blue</div>
            `
        });
        app.mount("#michael");
    </script>
