takeOrder('bacon', 'thin crust');
takeOrder('mushrooms', 'pan crust');
You may also consider adding spacing to your console.log message like this. This way when console returns the message the spacing is correct.
console.log('Order: ' + crustType + ' pizza topped with ' + topping);
Not sure if this helps but when I was starting down the JS path, if the code fails, I would copy the code, open a new tab, open the browser developer tools (F12 Chrome) and go to console. Then I paste the code in there and run it. If the code fails there is usually an error message that I would use to track down the issue.
