These coding challenges are very specific; In this case you are asked just to check if "JavaScript" is the answer, don't use toLowerCase(). They want your answer to be "JavaScript" not "javascript".

var answer=prompt('What is the best programming language?');
if(answer ==="JavaScript"){
alert("You are correct");
}

Even this won't work

 var answer=prompt('What is the best programming language?');
if(answer==="javascript"){ //lowercase
alert("You are correct");
}
