Description

Objective
This assignment will help you practice JavaScript syntax, and use built-in and user-defined functions.
Please do this assignment on your own, and submit only your own work. Gaining experience with JavaScript and the web takes a lot of personal practice, and working on these problems yourself will help build your skill.
Instructions
Below you will find various tasks that need to be completed. Write your solutions in a file named assignment01.js. You can use the Firefox Scratchpad to run your code, or use node.js.
Make sure you properly format all your code with correct indenting and spacing, declare all variables before first use, include semi-colons, etc. You will lose marks if your code is not properly written.
Task 1 – Format and Display Student Info
Write an implementation for the following function:
function displayStudentInfo(name, program, courses, hasJob) { }
Your function should format the data passed to it, and display this info to the console as a formatted string. Your function should work as shown below. A few things to note:
• The final argument `hasJob` is optional, and should be used to determine whether you display “do” or “don’t” regarding the student’s part-time job.
• Depending on the value of `courses`, use either course (1) or courses (more than 1). displayStudentInfo(“Jane Doe”, “CPA”, 5);
“My name is Jane Doe and I’m in the CPA program. I’m taking 5 courses this semester, and I don’t have a part-time job.” displayStudentInfo(“John Kim”, “BSD”, 1, false);
“My name is John Kim and I’m in the BSD program. I’m taking 1 course this semester, and I don’t have a part-time job.” displayStudentInfo(“Vivian Lee”, “CPA”, 3, true);
“My name is Vivian Lee and I’m in the CPA program. I’m taking 3 courses this
semester, and I do have a part-time job.”
Task 2 – Calculate Age Statistics
Write an implementation for the following function:
function calculateAgeStats(birthDate) { }
“You were born on Sat Dec 23 2000 and have been alive for approximately 155316 hours.”
Task 3 – Convert Temperatures From/To Celsius & Fahrenheit
Write an implementation for the following function to convert temperature values for a given scale:
function convertTempFrom(value, scale) { }
Your function should convert the `value` (a Number) from the given `scale` (a one character String indicating Celsius (“c” or “C”) or Fahrenheit (“f” or “F”)) to the other scale. If no scale is given, assume the scale is Celsius and return a value converted to Fahrenheit. If the scale is unknown, return an error string:
// NOTE: values updated from previous version for conversion calculation.
convertTempFrom(50); should return “122 F” convertTempFrom(50, “c”); should return “122 F” convertTempFrom(50, “C”); should return “122 F” convertTempFrom(14, “f”); should return “-10 C” convertTempFrom(10, “F”); should return “-10 C”
convertTempFrom(56, “G”); should return “ERROR: Unknown Scale – G” convertTempFrom(56, “k”); should return “ERROR: Unknown Scale – k”
Task 4 – Display Odd/Even for all numbers in a range
Write an implementation for the following function to print all numbers in a given range, and whether they are odd or even:
function displayOddEven(rangeStart, rangeEnd) { }
Your function should loop through all numbers in the range given, and print to the console whether or not the number is odd or even:
displayOddEven(0, 10);
0 is even
1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
10 is even
Task 5 – Find Largest Number
Write a function named findLargest as a function expression which takes any number of values (Numbers) and returns the largest number. Your function should work like so:
findLargest(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)); should return 10 findLargest(-1, -2, -3, -4, -5, -6, -7, -8, -9, -10)); should return
-1
findLargest(200, 313, 5000, 2, -10, 9993513, 3, 2)); should return 9993513
Task 6 – Average Evaluator
Write a function named calculateAverage as a function declaration which takes any number of values (Numbers), and returns their average. Your function should work like so:
calculateAverage(1, 2); should return 1.5
calculateAverage(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); should return 5.5 calculateAverage(77.2, 89, 57.4, 100, 62, 73, 87, 90); should return
79.45
Task 7 – Class Grades
Write a function named formatGrades as a function declaration which takes any number of scores (Numbers) and formats them as letter grades. Within your formatGrades function, write a function expression named letterFromScore which takes a single score (Number) and returns a letter grade (String). Use a loop to call letterFromScore for each of the scores passed to formatGrades. Your function should work like so:
formatGrades(77.2, 89, 57.4, 100, 62, 73, 87, 90) should print: B A D A+ C B A A+
