Complete Intro to Computer Science
modified
- Author
- Brian Holt (Frontend Masters)
- Used
- 21 lessons: Big O, spatial complexity, trade-offs, the sorts, binary search, recursion, lists, Bloom filters, trees, traversals, graphs, pathfinding; their images, GIFs and the AVL/radix/linked-list videos.
- Changed
- Modified: re-laid out in this site's templates, media served locally, author photos / Frontend Masters logo / course housekeeping removed, CodeSandbox badges turned into link rows. The intro, exercises and wrap-up pages are not reproduced.

- Used
- 26 exercises: directions, examples, stubs, tests, completed solutions and every commented-out alternate solution.
- Changed
- Nothing. Files are reproduced verbatim from the pinned commit; alternates only have their leading comment markers removed for display. The `events` exercise is skipped (no solution in the repo).

- The other 363 pages: 66 runnable JavaScript sheets (algorithms, JavaScript, design patterns, OWASP, post-mortems, project skeletons) and the reference sheets (complexity cheat-sheet, system design playbook, concepts, walkthroughs, web-vulnerability quick reference); the nine-language polyglot track, the four frontend walkthroughs and the React cheatsheet; the system design primer; the mindset articles; the naive/optimal pairs; every section intro, diagram and verification note — and the site itself.
- Changed
- Language and frontend pages were rewritten and re-verified against current official docs in 2026 (each page lists what changed). Everything else is published as written; dead hosted images were replaced by diagrams made for this site, and the naive/optimal demo was ported from the DOM to asserts so it runs in the browser worker.
