将三元运算符的变量转换为if-else语句

Question

x = (year % 100 === 0) ? (year % 400 === 0) : (year % 4 === 0);  
alert(x);

大家好，如何将此变量x转换为if-else语句，以true或false结果返回变量？

非常感谢

Answer 1

year = 2010;

if(year % 100 === 0)
    x = (year % 400 === 0);
else
    x = (year % 4 === 0);  
alert(x);

if(year % 100 === 0)
    x = (year % 400 === 0);
else
    x = (year % 4 === 0);  
alert(x);
