DSA Notes
A focused, twenty-chapter reference for data structures and algorithms in JavaScript, built for quick review before interview day.
The Brief
Give engineers a single, distraction-free reference for core DSA concepts in JavaScript, with a way to track what they have already reviewed.
The Challenge
Engineers preparing for interviews often relearn data structures and algorithms from scattered blog posts, video courses, and platforms that bury the actual concept under unrelated production, ads, or a sign-up wall.
Most of that content is built for a first pass through a topic, not a fast, structured review the night before an interview.
Our Approach
We built a lightweight, twenty-chapter reference site that gets straight to each concept, with per-chapter read tracking and display controls suited to quick review sessions.
- 20 chapters covering core data structures and algorithms in JavaScript
- Per-chapter read tracking with a one-tap progress reset
- Adjustable content width and theme controls for comfortable reading
- No sign-up: progress stored locally in the browser
Scope of Work
- Twenty-chapter DSA reference site
- Chapter read and progress tracking
- Width and theme display controls
- Fast static build for instant page loads
The Outcome
DSA Notes gives engineers a fast, ad-free reference they can work through chapter by chapter and pick back up exactly where they left off.
