Where is your for loop for which you're an index i? If its removed intentionally then Tucson in your array has a space in the end. Use trim method.

Also language = "javascript" is wrong, its usually type="text/javascript"

The code should be like below:

enter code here
var cleanCities = ["Cheyenne ","Santa Fe ","Tucson ","Great Falls ","Honolulu"];
var cityToCheck = "Tucson";
for(var i=0; i<cleanCities.length; i++) {
   if(cityToCheck === cleanCities[i].trim()){
    alert('you are clean');
   }
 }
