Can you, answer the questions below and then send me your SID, that is, send me your college ID?

I’m expecting to see Node based code that will run at the command line, but if you don’t know about Node, then create code that would work in a browser. Do the best you can, you don’t necessarily have to get everything right to get in the course, but I want to see what you can do.

Question One:

Create an example function called boatFromMastCount that takes a parameter called numberOfMasts and returns the word schooner if numberOfMasts is set to 2 and sloop if numberOfMasts is set to 1. Write the function twice, once with if-else statements and once with a switch statement. Name the two versions as follows:

  • boatFromMastCountIfElse
  • boatFromMastCountSwitch

Call both functions and display their output.

When complete, we should be able to call it like this:

var result = boatFromMastCountIfElse(2);


That code should produce this output:


Question Two

There are two ways to create JavaScript objects. One uses curly braces:

var qux = {};

The other uses function syntax:

function() {}

Create a JavaScript object with two properties called kind and model. Provide two examples of the object, one using JavaScript Object syntax and one using JavaScript Function (constructor) syntax.

Question Two Part I

First create the object using JavaScript object syntax { … }.

The declaration should have two properties called kind and model initialized to empty strings. After declaring the object, add the following code that uses the object:

ship.kind = 'sailboat';
ship.model = 'schooner';


The code should produce this output:

{ kind: 'sailboat', model: 'schooner' }

I’m looking for a declaration of ship using object (curly brace) syntax that supports the code shown above. How should ship be declared so that the above code will compile and run as shown?

Question Two Part II

Now create a second instance of the object called Boat, but this time use function constructor syntax. If we use the function object like this:

var boat = new Boat('sailboat', 'schooner');


Then it should produce this output:

Boat { kind: 'sailboat', model: 'schooner' }

What I’m looking for is the declaration of Boat that would create the behavior described above. How should Boat be declared?

Question Three

What do the following commands do:

mkdir ~/Git/writings/Tech/StudentCodeQuiz
mv foo.js ~/Git/writings/Tech/StudentCodeQuiz/.
cd ~/Git/writings/Tech/StudentCodeQuiz/
git add .
git commit -m "Initial commit of student quiz code"

Again, you don’t have to know the answer, but at least take a guess.
