问题描述
我想知道是否存在&"Javascript中的逻辑运算符.我尝试运行1&0和1&&在Firebug(Firefox)中为0，并且两者都返回0.
I was wondering if there is a "&" logical operator in Javascript. I tried running 1 & 0 and 1 && 0 in Firebug(Firefox) and it returned a 0 for both.
有人告诉我C#同时接受&和double&&&&&&< 效率更高，因为一旦遇到错误，它将退出比较循环，但是我无法找到有关Javascript的任何信息.
Someone told me that C# accepts both & and double &&, double being more efficient as it will exit the comparison loop as soon as a false is encountered, but I was not able to find any info for Javascript on that.
有什么想法吗?
推荐答案
否.& 是按位AND 运算符.&& 是Javascript中唯一的逻辑AND运算符.
No. & is a bitwise AND operator. && is the only logical AND operator in Javascript.
