1、

import export

export let A = 123;

export function test () {
  console.log('test')
}

export class Hello {
  test () {
    console.log('class')
  }
}

 

import {A,test,Hello} from '@/utils/module.js'

 

2、

 

let A = 123;

let test = function () {
  console.log('test')
}

class Hello {
  test () {
    console.log('class')
  }
}

export default {

}

 

import obj from '@/utils/module.js'
