Question

QUESTION 14

1. "Given this object, how would you assign the model to a variable named m?

   var myCar = {make: 'Plymouth', model: 'Valiant', year: 1968}"

   		myCar.model(m);
   		m = model.myCar;
   		m = model.model;
   		m = myCar.model;

QUESTION 19

1. This program will produce an error. Why?  

   var x;
   for(var i = 0; i < 12; i++) {
      x = x + 2;
   }

   		the variable i is illegally declared
   		there is an attempt to read the value of x before x has been assigned a value
   		the for-loop will never execute
   		this program will not produce an error

QUESTION 20

1. How many times will this loop execute?
   
   var x = 0;
   for(var i = 8; i >= 3; i--) {
      x = x + 2;
   }

   		7
   		5
   		6
   		0
