Deep JavaScript Foundations, v3 vs Complete Intro to Web Development v3
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

Complete Intro to Web Development v3
Per-criterion
Reviewers consistently describe the curriculum as the deepest treatment of core JavaScript available in video form. The three pillars — types and coercion, scope and closure, and the this/prototype object system — are explained directly from the language specification rather than from surface behaviour. Gurpreet Singh's testimonial captures the consensus: "I know of no other resource that goes this deep into fundamentals of JS." The main critique is that some sections, particularly the OLOO delegation pattern in the object-oriented module, are presented as settled best practice when many experienced developers disagree.
Kyle Simpson, author of the You Don't Know JS book series, is widely praised for clarity and depth. Lara Karki called him "not only brilliant, but an excellent and articulate teacher" and Hatem Hassan noted he "has a unique way of explaining deep technical CS concepts in a simple and straightforward manner." The score is held below the instructor scores of less polarising teachers because his opinionated, prescriptive style draws genuine criticism — one HN commenter found his persona "very off-putting" and others object to his advocacy for == coercion.
The course is bundled into the Frontend Masters subscription at $39/month or $390/year, which also unlocks the entire library including Kyle's scope, closures, and asynchronous JavaScript courses. Lara Karki called the membership "the best $40 I'll spend this month, by far." Value is excellent for committed learners but the subscription model means a single 10.5-hour course is not buyable standalone, which frustrates learners who only want this one title.
The course makes developers materially better at reading and reasoning about production JavaScript — Kevin O'Shaughnessy noted it "blew my mind how much there was going on in 10 lines of code." However, it is conceptual rather than project-based: there is no application built end to end, no framework, and no tooling. Reviewers who wanted to ship something tangible note that this is a foundations course, and its payoff shows up later as fewer bugs and clearer mental models rather than a portfolio piece.
Frontend Masters provides downloadable exercise files, transcripts, and a hosted course platform with adjustable playback speed, but there is no graded auto-grader, no mentor, and no certificate. Learners rely on the public GitHub note repositories and exercise mirrors that other students have published. This is a lecture-and-exercise format, not a guided cohort, so self-directed learners do best.
HTML, CSS, JavaScript fundamentals plus a Wordle-clone capstone across roughly 12 hours 25 minutes. Praised as thorough for absolute beginners, but v3 was published in September 2022 and several modules predate modern CSS practices and the current Vite-driven tooling stack.
Brian Holt is the most consistently praised aspect across nearly a decade of Hacker News mentions. Even on the original v2 Show HN thread, commenters described his teaching as 'very good', 'thorough', and 'great' — the same words that recur in his React course discussions.
Requires a Frontend Masters subscription ($39/month) for a beginner curriculum that overlaps heavily with the free freeCodeCamp Responsive Web Design path and The Odin Project. The course notes on Holt's GitHub site are free, which partially offsets the paywall.
The Wordle-clone capstone is the only build-along project and ties HTML, CSS, JS and the DOM together cleanly. Less portfolio leverage than freeCodeCamp's five required projects, and pushes less on local dev environment than The Odin Project.
Strong foundation in browser fundamentals and a deliberate 'Git and Bash' module that competitors often skip. Weak on modern tooling depth — bundlers, package managers, deployment — which learners are expected to pick up in Holt's follow-on React course rather than here.
Scoring methodology applies identically to every course on the site — see the formula.
