Here comes the main Logical operators used in JavaScriptLogical AND (&&)This will return true if both operands are true.Example as followsvar a = true; var b = false; var result = a && b; // result is false JavaScript CopyHere both a and b are not true so the value of result ...
For example,// NOT on true console.log(!true); // false // NOT on false console.log(!false); // true // comparison example console.log(!(2 < 3)); // false Run Code Here,!true results in false because ! inverts the value of true to false. !false results in true because !
