Learn HTML vs Complete Intro to React v9

The curriculum covers HTML elements and structure, tables, forms with HTML5 validation, and semantic HTML across roughly four lessons and seven-to-nine hours of work. Reviewers consistently call it clear, well-structured, and genuinely understandable for people who have never touched code. The honest ceiling is depth: it is a fundamentals tour, not an advanced reference, and it teaches markup in isolation from the CSS and JavaScript that turn markup into a finished site.

There is no single named instructor — Codecademy uses a curriculum-by-committee model delivered through short written lessons, a three-panel code editor, and an AI Learning Assistant that gives instant feedback. That format is excellent for syntax drilling and keeps beginners moving, but several reviewers note the lack of a human voice explaining the why, and that the auto-grader can be unforgivingly strict about exact syntax.

As a standalone credential the impact is modest. The certificate is paywalled and, as multiple reviewers stress, not accredited — proof of completion rather than a verified qualification employers weigh heavily. HTML fundamentals are a real and necessary first rung, but on their own they do not make anyone employable; the career value comes only when this feeds into CSS, JavaScript, and project work.

The lessons interleave guided practice and mini-projects, and learners praise how the practice makes retention noticeably easier. But the independent, portfolio-building projects are a Pro feature, and the free tier is repeatedly described as failing to guide you on applying the knowledge once the lessons end.

The core Learn HTML lessons are genuinely free, which is the single strongest argument in the corpus. The certificate of completion and the portfolio-grade projects require a Plus or Pro subscription (roughly $15-$40/month depending on plan and billing). For a fundamentals intro the free tier alone is hard to beat on price, though reviewers are clear that free content stops short of the projects that consolidate learning.

v9 covers React 18 and 19 features (form actions, Suspense, the React Compiler) plus a modern Vite + TanStack Router + TanStack Query stack. Praised for currency, with a minority of long-term Frontend Masters subscribers flagging that other courses in the catalog can drift.

Brian Holt is the most consistently praised aspect across nine years of Hacker News mentions. Learners use words like 'excellent', 'great', and 'brilliant'. His pet adoption project framing is repeatedly cited as memorable.

Requires a Frontend Masters subscription (currently $39/month), which is consistently described as worth it if you complete more than one course per month. Less competitive against free alternatives if you only want a single React intro.

The single build-along project (an e-commerce app in v9, evolved from the pet adoption app of earlier versions) is praised for being non-trivial and integrating real ecosystem tools (TanStack Query, Vitest) rather than toy examples.

Holt spends real time on tooling (Vite, ESLint, Prettier, code-splitting, Vitest) and modern ecosystem choices, which is the single most-cited reason people say his courses transferred well to their day jobs.
