Array, prompt, if, if else statement

  1. UserGuess must be userGuess. Because javascript is case sensitive.
  2. You turned the output of prompt to lower case. it's okay. but you forgot to turn the elements of the array to lower case.

You have a syntax error where you are using userGuess instead of UserGuess. Moreover, the purpose of using toLowerCase() is to remove the case sensitivity between the two strings when comparing, whereas what you are doing is changing the input to lower case while keeping the array elements to have some uppercase letters. Here is the solution:

var myBands = ["chromatics","acdc","michael jackson"];
var UserGuess = prompt("Who is your favourite?");
var userGuessLower = UserGuess.toLowerCase(); 
if (myBands.indexOf(userGuessLower) === -1) {
     alert("Na They're pretty lame.");
}else {
     alert("OMG I love them too!");
}
