Why don't bitwise operators work?

Question

JavaScript

There is an expression:

var summidle=3
  var sum=16 

  if ((sumidle==3) & (summ>11 & sum<22)){
    alert("legend")	
  }

But the legend is not displayed, it seems to me that it is not displayed because the problem is in the bitwise operators "Maybe I entered them wrong" , who can explain why, please explain.

Answer 1

You have a typo in the comparison operation - sumidle. – and summidle is declared.
