curTermYear = year lastTermYear = (lunarDate.cDay - curTermDay) < 0 ? year - 1 : year nextTermYear = year以上代码将同一个数据传值给不同变量,这样做是否会出错?如是,请改正

这种情况下,如果数据类型为基本数据类型(如int、float等),则不会出错,因为数据传递的是值,而不是引用。但是,如果数据类型为对象,那么在不同变量之间传递时,会传递对象的引用,可能会导致意外的更改。为了避免这种情况,应该使用拷贝构造函数或赋值运算符来创建一个新的对象,而不是直接将引用传递给另一个变量。例如:
```
curTermYear = year;
lastTermYear = (lunarDate.cDay - curTermDay) < 0 ? year - 1 : year;
nextTermYear = year;
```
在这个例子中,我们只是将基本数据类型的值传递给不同的变量,所以不需要改变代码。

lastTermMonth = {lunarDate.cMonth - 1 = 0 ? 12 : lunarDate.cMonth - 1}以上代码的正确写法是什么?
这段代码有语法错误,应该将等号改为冒号,正确写法如下:
```
lastTermMonth = lunarDate.cMonth - 1 == 0 ? 12 : lunarDate.cMonth - 1;
```
这段代码使用了三目运算符,根据当前农历月份 `lunarDate.cMonth` 计算上一个节气所在的农历月份 `lastTermMonth`。如果当前月份为1月,则上一个节气所在的月份是12月。否则,上一个节气所在的月份为当前月份减1。
把以下代码改成if()和else if()解构: {lunarDate.cMonth == 1 && [5, 6, 7].includes(lunarDate.cDay) ? term1 = j[0] : null} {lunarDate.cMonth == 2 && [3, 4, 5].includes(lunarDate.cDay) ? term1 = j[1] : null} {lunarDate.cMonth == 3 && [5, 6, 7].includes(lunarDate.cDay) ? term1 = j[2] : null} {lunarDate.cMonth == 4 && [4, 5, 6].includes(lunarDate.cDay) ? term1 = j[3] : null} {lunarDate.cMonth == 5 && [5, 6, 7].includes(lunarDate.cDay) ? term1 = j[4] : null} {lunarDate.cMonth == 6 && [5, 6, 7].includes(lunarDate.cDay) ? term1 = j[5] : null} {lunarDate.cMonth == 7 && [6, 7, 8].includes(lunarDate.cDay) ? term1 = j[6] : null} {lunarDate.cMonth == 8 && [7, 8, 9].includes(lunarDate.cDay) ? term1 = j[7] : null} {lunarDate.cMonth == 9 && [7, 8, 9].includes(lunarDate.cDay) ? term1 = j[8] : null} {lunarDate.cMonth == 10 && [8, 9].includes(lunarDate.cDay) ? term1 = j[9] : null} {lunarDate.cMonth == 11 && [7, 8].includes(lunarDate.cDay) ? term1 = j[10] : null} {lunarDate.cMonth == 12 && [6, 7, 8].includes(lunarDate.cDay) ? term1 = j[11] : null}
