How can a prompt dialogue box accept either a answer in as a number or string using the if/else conditional.

//This is my example
// 2. Ask user a questions
var questionTwo = prompt("How many wheels does a car has?").toLowerCase();
// 2. Answer of questions
var answerTwo;
   if (answerTwo === '4' || answerTwo === 'four'){ 
    answerTwo = true;
   }  

if (answerTwo === questionTwo){
    document.write('<p style="color:green;">You are correct!</p>');
    } else {
    document.write('<p  style="color:red;">That\'s incorrect!</p>');
 }

Hey Darren Joseph,

I edited your code so that it would render better. Here's how I did that:

code

A much better way to get what you need done is to check to see if questionTwo is equal to one of those answers and write the code then and there instead of wasting memory setting an answer variable. You make the code much more efficient that way. 

//This is my example
// 2. Ask user a question
var questionTwo = prompt("How many wheels does a car have?").toLowerCase();
// 2. Answer of question
   if (questionTwo === '4' || questionTwo === 'four'){ 
    document.write('<p style="color:green;">You are correct!</p>');
   }  
else {
    document.write('<p  style="color:red;">That\'s incorrect!</p>');
 }
