Prim's Algorithm: Quick Guide with Examples
This free guide, Prim's Algorithm: Quick Guide with Examples, an accessible introduction to one of graph theory’s most important optimization techniques. It covers the fundamentals of graphs, weights, spanning trees, and minimum spanning trees, and then demonstrates how the algorithm incrementally builds a network by always selecting the lowest-cost edge that expands the tree.

The Quick Guide to Dijkstra's Algorithm
The Quick Guide to Dijkstra’s Algorithm explains one of the most widely used algorithms in computer science for finding the shortest path in a graph. The guide covers how Dijkstra’s Algorithm systematically selects the least costly path from a starting point to all other nodes, making it essential for navigation, logistics, networking, and more. Readers are introduced to key concepts like graphs, weights, and priority queues, and then shown how the algorithm works step by step with practical examples.

Practical Math for Frontend Developers
Practical Math for Frontend Developers is a 65-minute intermediate-level course that teaches essential math skills through hands-on coding. Instead of abstract formulas, students immediately apply concepts by building three projects: a shopping cart with tax calculations, a weekly scheduling app using the Date object and array methods, and a monthly expense sheet that ties everything together. With interactive challenges built into the course, learners practice applying math directly in the context of frontend development.
