Talking about boolean value

【Foreword】

    Seeing a js interview question is very basic, but it is still easy to confuse newcomers. Record it here and emphasize it in future lectures

    The following is my personal understanding, if there is any misunderstanding, please correct me

 

【main body】

   When learning js, you should have learned the boolean value, and general textbooks will give relevant explanations, such as

boolean has two cases
true and false
and
0 and 1, 0 for false, 1 for true

 So here's a question

 Interview questions:

var request = 1>2;
if(request==666){
   console.log('aaa')
}else{
   console.log('bbb')
}

 The answer is: bbb, which reminds me of a student who asked me before about Boolean = 2

 

【Analysis】

   The easy confusion here is the judgment condition ( boolean=666 )

   In fact, just remember that 0 is false, and non-0 is true. And 1=true in the tutorial is just a commonly used value, don't confuse it here
