3. 日期对象比较大小

   相等的比较 ???var date1 = new Date(); ???var date2 = new Date(); ???console.log(date1.valueOf() === date2.valueOf()); ?// true大小的比较，直接用比较运算符操作 ???var date1 = new Date(); ???var date2 = new Date(date1.valueOf() + 10); ???console.log(date1 < date2) // true

4. 时间间隔

   计算两个日期间隔多少秒var date1 = new Date();var date2 = new Date(date1.valueOf() + 5000);var diff = date2.valueOf() - date1.valueOf();var diffsecond = diff/1000console.log(diffsecond); ??// 5
