UMD判断amd和commonJS有先后顺序吗？

Question

exports这个对象在amd中也可能存在啊
为啥看到有的代码先判断commonJS模块？

Answer 1

就像平时的:if(x&nbsp;>&nbsp;y){&nbsp;&nbsp;&nbsp;&nbsp;//&nbsp;dosomething...}else&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;//&nbsp;other...}可以写成：if(x&nbsp;<=&nbsp;y){&nbsp;&nbsp;&nbsp;&nbsp;//&nbsp;other}else&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;//&nbsp;dosomething...}谢邀，这种判断不存在先后顺序吧，应该是看个人喜好先判断哪个(个人理解，仅供参考)
