最后返回的结果是:

{    default: function fn2(){    },    foo2: 1,    test3: {        default: function fn3(){        },        foo3: 1    }}

 

// app.js// import json from './1.json';import * as all from './test2';import fn2 from './test2';console.log(all);console.log(all.default === fn2); // trueconsole.log(fn2);// test2.jsfunction fn2(){    console.log(1);}export default fn2;var foo2 = 1;export {foo2};export * as test3 from './test3';// test3.jsfunction fn3(){    console.log(1);}var foo3 = 1;export {foo3};export default fn3;
