ECMAScript 中 的export 转发

// ----- head.js -----

export const eye = '纯洁的'
export const nose = '挺拔的'

export default {
    eye,
    nose
}





// ----- index.js -----

// 想实现
// import { eye, nose } from './head.js'
// export { eye, nose }

export { eye, nose } from './head.js'


// 想改名

export { eye as pureEye, nose as loftyNose } from './head.js'


// 把 head.js 所有的(default/eye/nose)导出

export * from './head.js'
export * as headObj from './head.js'

// index.html


    
    // 静态加载，后面无法拿到js里的变量
    

    // 要想和数据互动
