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

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, React, Node, Express, MongoDB, EJS, basic deployment) — wider than Colt Steele because React is in the main course. A recurring 2025 critique flags outdated sections that tripped up a zero-experience beginner.

Repeatedly described as beginner-friendly — "gets a basic understanding of dev in your head". The shared brand with her 100 Days of Python and iOS bootcamps anchors her as one of the most-recommended Udemy instructors for absolute beginners.

Listed near $200 but routinely buyable for $10-$15 on Udemy sales — the same pattern the corpus reports for every popular Udemy course. Every recommender we tracked explicitly names the sale price; no one pays sticker.

Many small build-along projects (Dicee, Drum Kit, Simon, Tindog, Newsletter Signup, Blog) plus a React capstone. Strong for keeping beginners motivated, weaker on a single non-trivial portfolio piece compared to Colt Steele's YelpCamp.

Includes a React section in the main course (the headline difference vs Colt Steele) and a separate MERN course as a follow-on path that one 2024 HN job-seeker credits with landing them at a TypeScript/ Next.js shop. Modern tooling, TypeScript and testing are still gaps.
