Question

How can I check if a variable's type is of type Boolean?(如何检查变量的类型是否为Boolean类型？)

I mean, there are some alternatives such as:(我的意思是，有一些替代方案，如：)

if(jQuery.type(new Boolean()) === jQuery.type(variable))
      //Do something..

But that doesn't seem pretty to me.(但这对我来说似乎不太好看。)

Is there a cleaner way to achieve this?(有没有更清洁的方法来实现这一目标？)

That's what typeof is there for.(这就是typeof是有。)

The parentheses are optional since it is an operator .(括号是可选的，因为它是一个运算符 。)

if (typeof variable === "boolean"){
  // variable is a boolean
}
