条件并列问题？

Question

if(condition == "con1" || condition == "con2")不能写成if(condition == "con1" || "con2")吗？

Answer 1

"con1" || "con2": "con1"是个字符串，相当于true，所以"con1" || "con2" == "con1"
if(condition == "con1" || "con2")你只是判断了condition == "con1"

Answer 2

不能，优先级问题
相当于

if((condition == "con1") || ("con2"))
