Javascript If Condition with multiple OR and AND

Question

please have a look on my if condition. I am just refreshing my javascript and I am wondering, how I could check, if the inserted variables, are the ones I want to be used.

Answer 1

function compare(choice1, choice2){
  var identical = choice1 === choice2;
  var options = ["rock", "paper", "scissors"];

  if (identical && (options.indexOf(choice1) > -1))
    alert("Pass");
  else
    alert("Not alike");

}

In this code, identical will be either true or false, and if it is true, you can check if it matches any of the values inside the options array.
