1.week和1.weeks之间有区别吗？

Question

1.week和1.weeks之间是否存在差异？或者它们是同义词吗？

Answer 1

来自Rails docs：

  

week()

     

别名：weeks

           

weeks()

     

返回与提供的周数匹配的Duration实例。

2.weeks # => 2 weeks

     

别名为：week

Answer 2

对于> 1.week == 1.weeks => true > 42.week == 42.weeks => true ，

week仅为an alias。

Answer 3

他们是同义词：
