使用动态扩展类表达式创建新元素

Question

是否可以将类表达式作为参数传递？还没有尝试过eval路线。// CardtsElements.Zone contains a valid class expression// used to create a valid Zone Custom Elementlet extend = (source, name, definitionClassExpression) =>     customElements.define('CARDTS-' + name,                            class extends CardtsElements[source] definitionClassExpression);                                                              ^^^^SYNTAX ERROR^^^^^^^^^^// Create a new 'CARDTS-FOUNDATION' element extending 'CARDTS-ZONE'extend('Zone','Foundation', {    static get observedAttributes() {        return ['suit','draggable','drop'];    }    constructor(){}});
