將三元運算符的變量轉換為if-else語句

Question

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

嗨，大家好，如何將這個變量x轉換為if-else語句，以返回true或false結果的變量？

非常感謝

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);
