顺便请教, is和instanceof有什么区别? 看到一些实例, 比如这里, 但是没有找到对它的详细说明文档.

这个 为类 的 实质作用是 确定 实例 对象的构造函数是与某 类是一样的

这个 is 是个 布尔型的 表达式 确认 "实例 是 什么类型" 这个身为 也不错

所以区别是, 如果A instanceof B, 那么A is B; 但是如果A is B, 不一定A instanceof B?

善后 - 这里给出的意思是"处理事务的后续问题，妥善处理事情发生后的遗留问题" 感觉蛮接近Finally的用途
导入 - 感觉Import和Export的作用是对应而且相反的, 那么中文最好也是对应而且相反?
InstanceOf - 如果它也可以用于接口, 比如
某某对象 instanceOf 某某接口, 那么为类好像就有点不全面? 不过身为个人感觉有点太拟人化, 但暂时没有想到其他的...
