Answer w/ a space = WRONG

// quiz begins, no answers correct
var correct = 0;

// ask questions
var answer1 = prompt("Name a programming language that's algo a gem.");
if (answer1.toUpperCase() === "RUBY") {
   correct += 1; 
var answer2 = prompt("Name a programming language that's algo a snake.");
if (answer2.toUpperCase() === "PYTHON") {
   correct += 1; 
var answer3 = prompt("What language do you use to style web pages?");
if (answer3.toUpperCase() === "CSS") {
   correct += 1; 
var answer4 = prompt("What language do you use to build the structure of web pages?");
if (answer4.toUpperCase() === "HTML") {
   correct += 1; 
var answer5 = prompt("What language do you use to add interactivity to a web page?");
if (answer5.toUpperCase() === "JAVASCRIPT") {
   correct += 1; 

// output results
document.write("<p>You got " + correct + " out of 5 questions correct.</p>");

// output rank
if (correct === 5) {
   document.write("<p><strong>You earned a gold crown!</strong></p>");
} else if (correct >= 3) {
    document.write("<p><strong>You earned a silver crown!</strong></p>");
} else if (correct >= 1) {
    document.write("<p><strong>You earned a bronze crown!</strong></p>");
} else {
    document.write("<p><strong>No crown for you. You need to study.</strong></p>");

For the first question (though this applies to all of them):

If I answer "ruby " with a space (" ") after "ruby", it will be wrong.

How can I fix this?

Thank you!

Hello Sebastian,

You can use the JavaScript method .trim() to remove excess whitespace from around a string. So, if someone answers " ruby ", you should be able to do the following:

answer = prompt("My question here!").trim()

When they enter " ruby ", the .trim() method removes the whitespace, leaving you with:

answer = "  ruby  ";


console.log(answer); // "ruby" instead of "  ruby  "

When the .trim() method is used, any string that the user puts into the prompt will have any extraneous whitespace removed and then stored into the variable "answer".

I hope this helps.


I'm not 100% sure of what you mean, but a space is a character, so in your conditional statement if there is no space after the word ruby, then in the prompt if you add a space it will return false not true.
