How to form a condition with a logical operator?

Question

JavaScript

Hello!
Changed the question a bit. You need to get the condition not with AND, but with OR.
There is an object:

var obj = {
    one  :  true,
    two  :  true
  };

How to form such a condition:
If there is one in the object OR one is not equal to false, then output something to the console?

Answer 1

if (obj.one || obj.one !== false)
console.log("test")
&& - and
|| - or
