Have you tried using your error console (F12 key)?
Suggest the following alterations:-
var ready = confirm("Are You Ready to Play",""); // all variables should be defined with the var keyword. (But whatever the answer the script proceeds)
var age = prompt("What's your age?", "") // Eliminate ugly "undefined" in prompt.
(But what if user responds "Mickey Mouse" or whatever (not a number)?)
var userAnswer = prompt("Do you want to race Bieber on stage?","");
if ( userAnswer == "yes" ) // = is assignment, == is comparison. "yes" must be in quotes as it is a literal string. if (userAnswer == yes) compares the answer with the value of a variable named yes (which does not exist).
(but what if user responds Yes or YES or Y?)
Be aware also that prompts and alerts are long obsolete, and should be used only for testing purposes. Not for obtaining responses from and/or displaying messages to your users.

All the code given in this post has been tested and is intended to address the question asked.
Unless stated otherwise it is not just a demonstration.
