html里直接引用es6的js代码(不通过webpack等打包工具)

<script src="https://cdn.jsdelivr.net/npm/es6-module-loader@0.17.11/dist/es6-module-loader.js"></script>

// mymodule.js:

export class q {
    constructor() {
         console.log(‘this is an es6 class!‘);
    }
}

<script type="module">

    import { q } from ‘mymodule‘;

    new q(); // -> ‘this is an es6 class!‘

</script>
