1.按位与(AND)& &将二进制数中相应的位按照特定的方式组合并运算,如果相应位全为1,结果为1,如果任意位为0,结果为0。 // The binary representation of 1 is: 00000000 00000000 00000000 00000001// The binary representation of 3 is: 00000000 00000000 000
// 添加一天const tomorrow = date.add(1, 'day');console.log(tomorrow.format('YYYY-MM-DD')); // 输出:2023-07-05// 减去一个月const lastMonth = date.subtract(1, 'month');console.log(lastMonth.format('YYYY-MM-DD')); // 输出:2023-06-04// 比较日期const otherDate = moment('2023-...

1. 2. 3. 4. 注意, 创建一个新Date对象的唯一方法是通过 new 操作符,例如:let now = new Date(); 若将它作为常规函数调用(即不加 new 操作符),将返回一个字符串,而非 Date 对象。 获取当前时间 复制 constcurrentDate=newDate(); 1. 如果不向 Date 构造函数传递任何内容,则返回的日期对象就是当前...
