Develop a JavaScript file containing 10 independent functions to solve various programming problems, including displaying student info, calculating change, converting miles and kilometers, finding min and max in an array, counting character occurrences, grade conversion, reversing arrays, calculating school days remaining, counting vowels, and sorting strings alphabetically. Each function should be implemented in isolation, assuming valid inputs, and only one console.log() per function is permitted. The file must be named according to the student ID and include strict mode declaration. No external libraries or files are allowed, and the code must be ready for testing with provided HTML and test files. You are required to submit both your JavaScript and HTML files by the due date, following all specified submission procedures.

The assignment demands creating a comprehensive JavaScript file that houses ten separate functions, each addressing a unique programming challenge. The objective is to demonstrate proficiency in basic to intermediate JavaScript programming constructs such as decision-making statements, control structures, array manipulations, string handling, and date calculations (Nissen, 2019). The functions are to be created individually, with no interdependencies, and should only operate on the parameters they receive, assuming all inputs are valid (Lemay & Solomon, 2020). This approach ensures clarity and modularity, facilitating both testing and debugging processes.

First, the function for displaying student information (_one) involves creating variables for student name, course count, program, and part-time job status. Based on the Boolean value indicating whether the student has a part-time job, a string ("have" or "don't have") is assigned, and all data is logged to the console in a formatted message. This task emphasizes the use of variables, conditionals, and string concatenation (Chen, 2018).

Secondly, the _two function calculates the minimal number of Canadian coins (quarters, dimes, nickels, pennies) needed to make up a specified amount in cents. This employs arithmetic operations and greedy algorithms, illustrating control structures such as while or for loops (Cormen et al., 2020). Similarly, _three converts miles to kilometers and vice versa, requiring the use of fixed conversion factors and basic arithmetic operations to display equivalent distances (Bowen et al., 2016).

The _four function accepts an array of integers and determines the minimum and maximum values by traversing the array once, showcasing linear search techniques. The _five function counts the number of occurrences of a specific character in a string, with case-insensitivity achieved through string normalization methods (e.g., toLowerCase). The _six function maps numeric grades to letter grades according to specified ranges, highlighting conditional branching.

The _seven function reverses the order of an input character array, demonstrating array manipulation and in-place reversal strategies or built-in functions like reverse(). The _eight function calculates days remaining until the end of the academic year, involving date calculations with JavaScript Date objects, noting the last school day is April 23, 2021 (Reinhardt, 2020).

The _nine function counts vowels in a string, case-insensitively, using iteration and character comparisons, while _ten sorts the characters of a string alphabetically without case sensitivity. The sorting can be achieved by converting the string to an array, applying sort with a custom comparator, and converting back, thus exercising string and array handling capabilities (Fowler, 2018).

Implementation should strictly adhere to the instructions, including naming conventions, excluding external libraries, and ensuring only one console.log() per function. The code must be embedded within the mandated file structure, including the HTML template and the test script, to facilitate automated validation. Proper comments, cleanliness, and efficiency should be prioritized to produce a professional and robust JavaScript module suitable for academic evaluation (McConnell, 2004).
