info Description

This course serves as an introduction to programming models used to generate and support Web-based applications. The course covers markup, presentation, and front-end interactivity concerns through an in-depth examination of current client-side scripting techniques. Other topics include the document-object model (dom), event-driven programming, form validation, debugging, and asynchronous web processing.

list Learning Outcomes

Upon successful completion of this course, students will understand...

• how to alter the dom dynamically using JavaScript;
• how to asynchronously alter the dom via web interactions;
• how to write JavaScript programs using modern JavaScript syntax;
• how to dynamically handle form input;
• and, how to author semi-advanced, static web pages using a modern front-end web stack.

file_download Software Requirements

All the software required for this course is free and listed below.

Browsers (Mac and Windows)

Download all the browsers available at Browse Happy. Some students might also want Chrome Canary, Safari Technology Preview, Firefox Developer Edition, and Firefox Nightly. I use Firefox, Brave, and Chrome in class.

Git Client (Mac, Windows, Linux)

All in-class examples, assignments, and help is done via GitHub. Download the client for your computer here.

Text Editor (Mac, Windows, Linux)

The code you write will require a text editor. Although there are many on the market, such as Sublime Text (nagware), for example, vs Code (open source) is the only editor supported in class. Download the Linux, Windows, or macOS version from https://code.visualstudio.com/.

Node (Mac, Windows, Linux)

Node.js is the back-end JavaScript runtime environment that we’ll use alongside (and sometimes instead of) the browser to work with JavaScript. Download the latest stable release from nodejs.org and follow the default instructions. Note: Installing Node also installs npm, Node’s package manager.

EditorConfig (Mac, Windows, Linux)

EditorConfig is a tool that enforces consistent coding styles for everyone who works on a codebase. In our case, that codebase consists of all the examples in class and all the assignments you’ll submit throughout the semester. EditorConfig consists of an extension and a configuration file (.editorconfig) that goes in your home — or project — folder. Some editors and ides have EditorConfig built in. vs Code, unfortunately, is not one of them. Install the EditorConfig extension for vs Code from here, then download this .editorconfig file and place it in your home folder. Ensure the file name is exactly .editorconfig, starting with a dot and without a file extension.

ESLint (Mac, Windows, Linux)

ESLint is a JavaScript code linter that will help to make sure your code is free of errors and bad practices. Note: Before proceeding, you must have installed Node and NPM.

Once installed, launch The Terminal and initiate the configuration process: eslint --init. Configure ESLint according to the following settings:

• Sunday, 16 March – Saturday, 22 March 2025 (Week 9) — No class (Spring recess)
• Tuesday, 8 April 2025 (Week 12) — Last day to change to pass/no pass, or vice versa; last day to withdraw with a grade of W
• Tuesday, 6 May 2025 (Week 16) — Last day of classes

Note: Time permitting, I will make every attempt to cover the topics listed below in order. However, depending on the cadence of the class, some topics may be overlooked.

assignment Assignments

There are three homework-type assignments and one final project. (See the Grading section to better understand what percentage of your final grade each is worth.)

Note: Broken links in the list below will be updated once each assignment is assigned a due date.

1. Assignment 1
2. Assignment 2
3. Assignment 3
4. Final Project

info Grading

Your grade for this course will be computed using the following formula:

1. Assignments (45%)
   • Assignment 1 — 15%
   • Assignment 2 — 15%
   • Assignment 3 — 15%
2. Final project (45%)
3. Attendance and participation (10%)

To calculate your final grade, convert to decimal the percentages above and the grades you’ve earned. For example, if you got an 80 on the first assignment, a 93 on the second assignment, a 60 on the third assignment, a 100 on your final project, and 100 for attendance, then you’d use the following formula:

(.80 × .15) + (.93 × .15) + (.60 × .15) + (1 × .45) + (1 × .10) = 89%

I do not give grades; students earn them. The grade you earn is based strictly on the outlined formula clearly listed in this section.

This grading formula is unbending and will be adhered to strictly.

Important Note

Please do not try to negotiate a grade with me. By asking me to treat you favorably, you’re requesting that I put you above your classmates. Manage your time well; I do not accept late work.

balance Class Policies

• Consuming food in class. There is no eating inside our classroom, either during class or while on break. Eat before or after class. Drinks in covered containers, however, are allowed.
• Digital devices. Silence your mobile devices before class starts.

psychology No AI Use in Class

The use of generative ai tools is strictly forbidden in this course. All programming assignments — and any labs — associated with this course must be completed without the assistance of ai-generated content. This policy is in place to ensure that the work submitted is authentically yours and reflects your personal understanding and capabilities. Violations of this policy will be considered academic dishonesty and will be subject to disciplinary actions as outlined in the university’s academic honesty policy.

warning Academic Honesty

Cheating of any kind will not be tolerated in this course; make certain that all the work you submit is your own. Refresh your understanding of the college’s policy on academic honesty.
