module.error


如果 module.status'errored',则该属性包含模块在评估期间抛出的异常。如果状态是其他值,访问此属性将导致抛出异常。

【If the module.status is 'errored', this property contains the exception thrown by the module during evaluation. If the status is anything else, accessing this property will result in a thrown exception.】

undefined 不能用于没有抛出异常的情况,因为可能会与 throw undefined; 混淆。

【The value undefined cannot be used for cases where there is not a thrown exception due to possible ambiguity with throw undefined;.】

对应于 ECMAScript 规范中 循环模块记录[[EvaluationError]] 字段。

【Corresponds to the [[EvaluationError]] field of Cyclic Module Records in the ECMAScript specification.】
