Receiving an undefined error while trying to access each component in the browser console using Vue.js

When I run this code (

$vm0.$children.forEach(tab => console.log(tab.name));
) in the console, I am getting undefined. I am currently learning Vue.js and creating components for my project. Below is the HTML code snippet:

<!DOCTYPE html>
<html>

<head>
    <title></title>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.0/vue.js"></script>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bulma/0.5.1/css/bulma.css">
    <style type="text/css">body {padding-top:40px; }</style>
</head>

<body>
    <div id="root" class="container">
        <tabs>
            <tab name="About Us" :selected="true">
                <h1>Here is the content for About us tab.</h1>
            </tab>
            <tab name="About Our Culture">
                <h1>Here is the content for culture tab.</h1>
            </tab>
            <tab name="Contact tab">
                <h1>Here is the content for contact us tab.</h1>
            </tab>
        </tabs>
    </div>
    <script src="js/11.js"></script>
</body>
</html>

And here is my JavaScript code:

Vue.component('tabs', {
template: `
        <div>
            <div class="tabs">
              <ul>
                <li class="is-active"><a>Pictures</a></li>
                <li><a>Music</a></li>
                <li><a>Videos</a></li>
                <li><a>Documents</a></li>
              </ul>
            </div>
            <div class="tabs-details">
                <slot></slot>
            </div>
        </div>
`,
mounted() {
    console.log(this.$children);
}
});

Vue.component('tab',{
template: `
    <div><slot></slot></div>
`,
props: {
    name: { required : true }
}
})

new Vue({

el: "#root"

})
