禁止导出重名的模块

为什么? ​

在同一个文件中,使用重复的名称导出相模块,会导致运行时异常

建议 ​

请删除重复的模块导出语句.

错误示例 ​

js
export const foo = 'ranwawa';

export { foo }; // -> SyntaxError: Duplicate export of 'a'
export const foo = 'ranwawa';

export { foo }; // -> SyntaxError: Duplicate export of 'a'
js
const foo = 'ranwawa';
const bar = 'zhangsan';

export default foo;
export default bar; // -> Uncaught SyntaxError: Identifier '.default' has already been declared
const foo = 'ranwawa';
const bar = 'zhangsan';

export default foo;
export default bar; // -> Uncaught SyntaxError: Identifier '.default' has already been declared

正确示例 ​

js
export const foo = 'ranwawa';
export const bar = 'zhangsan';

export default foo;
export const foo = 'ranwawa';
export const bar = 'zhangsan';

export default foo;
