Question regarding last part of video relating to toUpperCase() method

Just out of personal curiosity, I tested the toLowerCase() method in the quiz.js workspace, but my code wouldn't pass if I used any upper case letters in my input. Does anyone know why toLowerCase() will not work like toUpperCase()? Should they work the same? I'll paste my code below: 

var answer = prompt("What programming language are you using right now?");
if (answer.toLowerCase() === 'javasript') {
  document.write('<p>You are awesome!</p>');
} else {
  document.write('<p>You are alright</p>');
}

It is perfectly fine to use the function on strings that are capital letters:

.toLowerCase()

The reason why your code did not run properly is because of the minor type error you made. Remember typo is very important!

here is the mistake, you said javasript rather than javascript

if (answer.toLowerCase() === 'javasript')
