The Last Algorithms Course You'll Need vs The Web Developer Bootcamp 2024

Across roughly nine hours and 60 lessons the course covers Big O time and space complexity, arrays, linked lists, queues and stacks, a ring buffer, recursion, the classic searches and sorts (linear, binary, bubble, quick), trees with BFS and DFS, heaps, maps, graphs with adjacency lists and matrices, and Dijkstra's shortest path. Reviewers repeatedly call it content-dense and "not the typical watered down content you find often on online courses." The honest mark-down is that it is implementation-first and fast — it condenses a full-semester CS course into under ten hours, so it favours breadth and live coding over slow, proof-heavy depth.

ThePrimeagen is the reason this course is so widely recommended. Reviewers describe his explanations as "full of joy and charisma," call him "an excellent communicator" who is "both down-to-earth and incredibly skilled and intelligent," and note that "you won't get bored and fall asleep." He implements most algorithms live rather than showing finished code, which learners consistently single out as the high point. This is one of the most engaging instructors in the DSA space and it shows in the 4.9/5 rating.

The course is completely free — all you need is a free Frontend Masters account — yet it sits behind, and is the same quality as, Frontend Masters' paid catalogue. For roughly nine hours of well-produced video plus a bespoke practice tool, reviewers call it "a worthy investment" and say "there is no other algorithm course that can teach you so many topics in such an efficient way." The only caveat on value is the subscription framing: the deeper Part 2 (advanced algorithms) sits behind a paid Frontend Masters subscription.

The standout practical feature is the kata-machine, a bespoke GitHub repository ThePrimeagen wrote that generates a fresh daily set of algorithm exercises with a ready testing environment, so you implement each structure from scratch in TypeScript rather than just watching. Learners praise this as the thing that makes the knowledge stick. The caveat is that there is no graded capstone or certificate, and some implementations (notably the doubly linked list) are "complicated, or rather convoluted, to implement," which can stall practice.

The stated goal is to teach enough DSA that, after practice, you could pass interviews at a large tech company, and reviewers report it delivered exactly that mental model — one four-year professional said "this was exactly what I needed to get back on track." The patterns (Big O reasoning, BFS/DFS, Dijkstra, the common sorts) are the bread and butter of coding interviews. But it is a foundation, not a credential: there is no certificate, and complete beginners will need significant outside practice before the interview goal is realistic.

Broad full-stack scope (HTML, CSS, JS, DOM, Node, Express, MongoDB) that shows beginners the whole shape of a web app. One recurring 2024 critique flags Udemy paid courses for "low effort updates" vs MDN or Odin.

Strongest criterion. Long-time HN users name Colt their "favorite web dev teacher" and credit his in-person classroom background. Signature move is walking students directly into mistakes then guiding them out.

Listed near $200 but routinely buyable for $10-$20 in Udemy sales — a price every commenter we tracked considers a giveaway given the runtime and lifetime access. The standard advice is to clear cookies, use incognito, and never pay sticker.

The build-along YelpCamp full-stack project (Express + MongoDB + authentication + image uploads) is the most-cited reason people finish the course feeling they built something real. Smaller mid- course exercises are praised as friction-removing but less portfolio-defensible.

Strong fundamentals on HTML, CSS, vanilla JS and a basic Node/Express/Mongo stack that transfers to most web roles. Weaker on modern tooling, TypeScript and React — most learners take a follow-up framework course to close the gap to a 2026 front-end job.
