创建javascript模块以从模块中导出函数、对象或原语值时，使用export语句，以便其他程序可以使用import语句。

export  name1, name2, …, nameN ;
export  variable1 as name1, variable2 as name2, …, nameN ;
export let name1, name2, …, nameN; // also var, const
export let name1 = …, name2 = …, …, nameN; // also var, const
export function FunctionName()...
export class ClassName ...

export default expression;
export default function (…)  …  // also class, function*
export default function name1(…)  …  // also class, function*
export  name1 as default, … ;

export * from …;
export  name1, name2, …, nameN  from …;
export  import1 as name1, import2 as name2, …, nameN  from …;
export  default  from …;
