In this two part challenge, I implement the Breadth-First Search algorithm in JavaScript. My demo application is "6 Degrees of Kevin Bacon" (finding the closest relationship between Kevin Bacon and another actor).

Breadth-First Search

In this video, I use the p5.js library to create a web-based countdown timer. I discuss the native JavaScript method setInterval() and well as p5’s millis().

JavaScript Countdown Timer

This multi-part coding challenge is part of the first week of my course: "Intelligence and Learning." Here I attempt to implement a classic data structure: The Binary Search Tree.

Binary Tree

I love all things random and chance so why not make a Plink simulation with the matter.js physics engine and p5.js!

Plinko with Matter.js

Inspired by Everest Pipkin’s Moth Generator, I use trigonometry and perlin noise to procedurally generate butterfly wing designs with p5.js.

Butterfly Generator

In this coding challenge, I look at extracting font path points from text in p5.js with p5.Font.textToPoints(). I render the text as particles with steering behaviors that react to the mouse.
