Brief notes on a 45 minute code-along I like to do to introduce P5.js, 3-D graphics, variables, objects, conditionals, and animation.
setup, replace line with createCanvas(500, 500, WEBGL);

Suppose the boss demanded a function to compute the area of a rectangle. The boss says the function MUST have four parameters, x1, y1, x2, and y2 where (x1, y1) is one of the corner points and (x2, y2) is the other corner point. But since our users can never remember what order the four parameters go in (Is it x1-x2-y1-y2 or x1-y1-x2-y2?), we will make our function REQUIRE that the four arguments in the call be “named.” Note that I said required. The function is not supposed to work if the arguments are not named. In fact, it should be an error to make a call without “naming” the arguments.
a) Write the function in JavaScript:
Disclaimer: I am not an auth expert, but I know someone who is. All errors and ramblings below are mine, not theirs.
First, some considerations:
Given a grid layout of Basic Latin letters as follows:
A B C D E
F G H I J
K L M N O
P Q R S T
U V W X Y
Z
Do all these problems without the aid of a computer, except where required to look up character names, character code points, and emoji data. The purpose of these exercises is for you to develop skills. If you spend the time to practice with pencil and paper (or a whiteboard) you will learn the material much better.
To submit your answers, copy the text below into a secret gist on GitHub and fill in the answers at the end of the same line. Email or DM me the url of the secret gist.
Make sure your Gist filename is CMSI284S2018HW2.md.
Your submission will be autograded so it is imperative that your answers are formmatted as expected. All encoded values should be in hex, not binary. Use the proper number of bits always; for example, UTF-32 answers must always show 8 hex digits, and characters should use the U+ prefix. MAKE SURE YOUR GIST HAS EXACTLY 50 LINES, NO MORE, NO LESS. Answers that are "correct" but not in the proper format will receive zero points, since answers that follow
