How to use the san.inherits function in san

const prefixCls = classCreator('collapse')();

const CollapsePanel = san.defineComponent({
    inited() {
        const showArrow = this.data.get('showArrow');
        const className = this.data.get('className');
        let classArr = [];

        className && classArr.push(className);
        !showArrow && classArr.push(`${prefixCls}-no-arrow`);
        this.data.set('className', classArr.join(' '));
    }
});

san.inherits(CollapsePanel, Collapse.Panel);
export default CollapsePanel;

san.inherits(Collapse, BaseCollapse);

export default Collapse;

import san from 'san';

import Radio from './radio';
const prefixCls = classCreator('radio-button')();

const radioButton = san.defineComponent({
    initData() {
        return {

    }
});

san.inherits(radioButton, Radio);
export default radioButton;
