ES2015 import & export

ES2015 import

  The import statement is used to import functions, objects or primitives that have been exported from an external module, another script, etc.

  用于导出已经声明为export的function、object。

  注意不存在import * from ‘module-name‘的用法,只能是import * as name from ‘module-name‘。

  注意导入export default,应当使用 import name from ‘module-name‘

  注意导入export,应该加上{},如import {name} from ‘module-name‘

ES2015 export

  The export statement is used to export functions, objects or primitives from a given file (or module).
