Not showing how many I got right

I'm making a quiz from JavaScript and when it reaches the end it shows you how many you got right. But it's not showing how many I got. This is the code I did:

var questions = ["What's the capital of France?", "What's 10 * 1000?", "If I have 5 apples in one hand, and 6 apples in the other, how many apples do I have?"]; var answers = ["paris", 10000, "11 apples"]; var answerToThis;

function quiz() { var correct = 0; for (var i = 0; i < questions.length; i += 1) { answerToThis = prompt(questions[i]); if (answerToThis.toLowerCase === answers[i]) { correct += 1; } } document.getElementById("final").innerHTML = "You got " + correct + " question(s) correct."; }

Then it comes up with 'You got 0 questions correct.' even though I got all of them.

When calling a method, you must put parentheses after the method name even if it takes no arguments (like "toLowerCase()").

Also, be aware that when using the type-sensitive comparison ("==="), a string (like you get back from "prompt") will not match a number even if they represent the same value.

Thank you for reminding me of that! I forget a lot sometimes... 😂
