Problem Set: Namespaces

This section contains a number of selected problems for the Namespaces section.

It is recommended that you review the problems, and complete a few before moving on to the next section.

Problem #1: What Does This Do?

The following code snippet prints out numbers from 10 down to 1, but this can be kind of tricky to figure that out at a glance.

Add a comment above the ||loops:for|| loop that specifies that this is what the loop does.

for (let i = 0; i < 10; i++) {
    console.log("" + (10 - i));


Change the loop structure above so that the same output can be achieved with just console.log("" + i); instead of console.log("" + (10 - i));: this would be much more readable, and likely would not need a comment.

Problem #2: How’s the weather

Create a weather namespace that contains variables that store information about the current weather. Include at least three variables in the namespace.

For example, this might contain the following variables:

Variable Current Value
condition “Cloudy”
chance of rain (percentage) 90
temperature (degrees Fahrenheit) 56
wind speed (miles per hour) 5

Include a short comment for each variable describing what the variable represents.

Outside of the weather namespace, ||game:game.splash|| a sentence describing the current weather.

Variables need to be exported to make them accessible outside of the namespace.

Problem #3: What About Barry

Create a barry namespace that has a few variables that contain information about Barry.

Make sure to include the following information:

Variable Current Value
name “Barry”
age 17
weight (lb) 1200
favorite food raw fish
status “Not a bear”

From outside of the barry namespace, console.log a description of Barry using the variables in the barry namespace.

Problem #4: Using Values

Inside the ||math:Math|| namespace, there are a few useful values related to Math. Use the ||math:Math|| namespace to ||game:game.splash|| the value of ||math:pi|| to the screen.

The ||math:Math|| namespace is one of the very few namespaces that starts with a capital letter. The standard convention for naming namespaces is to have the name be in lowercase letters.

Problem #5: A Few of My Favorite Things

Create a favorites namespace. Inside, define at least three variables that contain information about your favorite things.

For example, it might store:

  • Your favorite color
  • Your favorite flavor of ice cream
  • Your favorite song
  • Your favorite number
  • Your favorite food
  • Your favorite movie

Right above the namespace, include a multiline comment that describes what the namespace contains. Make sure that this is immediately above the favorites namespace - no other code between the comment and the namespace

Outside of the namespace, console.log a sentence containing at least two of the variables defined in favorites.

Hover over the favorites namespace somewhere in your code. The comment you wrote before for the namespace should show up on the screen.
