Having issues with my document write 

var question = prompt('What programming language is the name of a gem?');
if ( answer === 'Ruby' ) {
    document.write("<p>That's right!</p>");
}

I'm getting this message in the JavaScript console and i'm not sure what it means.

Uncaught ReferenceError: answer is not defined

Your final code, should look like this:

var question = prompt('What programming language is the name of a gem?');
if ( question === 'Ruby' ) {
    document.write("<p>That's right!</p>");
}

The document write part is still not working. Very strange

Make sure to enter "Ruby" exactly like that, with the capital "R" so that it will be true in the "if" statement. I just tested it and it works. Good luck!

Either update the var name to "answer" or in your "if" statement, change "answer" to "question"

That's because you are saving the input into the variable "question" in the first line - instead of the variable "answer", which is compared with "ruby" in line 2.

I tried switching them around but it still wont work.

You shouldn't switch them, but make them the same variable :)

Line 1: put result of prompt into variable "question"

Line 2: Compare the variable that you put the input into (in this case "question") with the desired result
