Welcome to BHS Computer Science. If you are a student in the class, the first thing you need to do (and which we should have done in class) is set up your GitHub account.
Once you have a GitHub account, click “Log in to GitHub” below to proceed. Or you can click “Use anonymously” to play with the environment but you will not be able to save your work or submit assignments. (You can always log in later by clicking the at the top of the page.)
If you don’t have a GitHub account yet, please create one and then log in here for further instructions.
Congratulations! You have successfully connected this app to GitHub. However you are not yet a member of the GitHub organization for this class, something Mr. Seibel needs to set up for you.
This is your GitHub profile URL:
Click the clipboard icon to copy it and then submit it at this form so he can add you.
Congratulations! You have successfully connected this app to GitHub. And it looks like you have an invitation to join the GitHub organization for this class. You need to accept that invitation before you can proceed. The invite should be sent to whatever email you used when you created your GitHub account.
I see you are logged into GitHub and a member of the berkeley-high-cs GitHub organization. However there seems to have been some problem finishing the setup for your account. Please let Mr. Seibel know.
This is a tool for the BHS Computer Science class at Berkeley High School. It is intended to provide a simple environment for experimenting with Javascript without all the complexities of a full development environment such as ReplIt or Glitch which we may use later in the year.
It is also designed to take advantage of the browser’s ability to run Javascript natively. It does not need access to a server to run code making in extremely responsive even if the Wifi is flaking out.
Finally, under the covers it is saving work to a GitHub repository in a very simplified workflow that does not depend on immediately learning any git commands. Code written in this environment for each assignment is saved to a directory and branch specific to that assignment each time it is saved. Thus when the assignment is done, it is easy to go to GitHub and create a PR containing just the work on that assignment which can then be commented on and worked on further before it is turned in and merged to main.
You're all set! You don't need to worry about this yet but we have successfully created a GitHub repository for your work:
You can get to it any time by clicking on your GitHub username at the top-right of the screen.
This assessment consists of functions you need to write involving primarily boolean expressions. It is a closed book assessment. You should stay on this tab until you are done and there should be no talking. This assessment is about how much you understand. There are no automatic tests but you can use the REPL to test things yourself.
You can move through the questions with the arrows at the upper right
next to the 1 of indicator so if
you're not sure how to write one function move on to another one and
come back if you have time at the end. I want to see how much you do
know. Note: you can also click on
thingsLikeThis in these instructions and the questions to
copy them to the clipboard to avoid spelling mistakes. (I.e. click to
copy and then ⌘-v to paste wherever you want.)
When you are done, please click on your Github username above
and submit a GitHub pull request of the branch
and request me as a reviewer. Doing
this correctly is part of the assessment.
If you are unsure how to request a review, please ask for help!
Write a function named needHeavyCoat that takes two
boolean arguments, one that is true if a person is going outside
and the other that is true if they are somewhere cold, and
returns a boolean indicating whether they need a heavy coat
which they only need if they are going outside somewhere cold.
Write a function named needSunscreen that takes two
boolean arguments, one that is true if someone is going to the
beach and the other that is true if they are going skiing, and
returns a boolean indicating whether they need to wear sunscreen
which they need to do both at the beach and on the ski slopes.
Write a function named needMittens that takes two
boolean arguments, one which is true if a person is going
outside and the other which is true if they are somewhere warm,
and returns a boolean indicating whether they need to wear
mittens which they need if they are going outside somewhere that
isn’t warm.
Write a function named isVenomous that returns a
boolean indicating whether a snake on the island of Booleana is
venomous based on two boolean arguments, one which is true if
the snake is striped and the other of which is true if the snake
has a blue head. All striped snakes on Booleana are venomous as
are all of the unstriped snakes on the island except the
blue-headed Blooby Snake.
Write a function named okaySpeed that takes two
numeric arguments, one indicating the posted speed limit in
miles per hour and the other the speed a car is going, also in
miles per hour. It should return true if and only if the speed
is no more than ten mph below the posted limit and no more than
ten mph above the posted limit.
Write a function named twiceAsExpensive that takes
two numeric arguments, each indicating the price of an item you
are considering buying. The function should return true if and
only if the first item costs more than twice as much as the
second item.
Write a function named winningRecord that takes
three numeric arguments, a team’s number of wins, losses, and
ties. It should return true if the team has a winning record,
meaning it has won more than half of the games it has played.
Write a function named isMagicNumber that takes a
single numeric argument and returns true if the number is one of
the two magic numbers, 42 or 17. (For
10,000,000 extra credit points, include a comment about why you
think 42 and 17 are magic numbers.)
