JavaScript Essential Training vs Intermediate React, v6: React Server Components, Hooks & Performance

The 2021 redesign covers variables, data types, objects, arrays, functions, loops, conditionals, DOM selection and manipulation, event listeners, and closures across roughly 6 hours 14 minutes of video. Reviewers praise the modern ES6+ syntax used throughout and the logical, progressive structure. The course's "objects first" ordering — starting with objects and methods before covering data types and functions — is polarising: blog reviewers like Nick Simson praise it as an accurate reflection of how modern learners encounter JavaScript through frameworks, while some beginners on the LinkedIn Learning platform found starting with complex concepts challenging. Multiple sources note that 11 quizzes and CoderPad code challenges provide genuine interactivity that many comparable beginner courses lack.

Morten Rand-Hendriksen is described consistently across review sources as clear, concise, and methodical. The topfreereviews.com team analysis credits him with giving "clear and concise instructions so that learners could follow the course without troubleshooting." The nicksimson.com blog review notes his deliberate pedagogical philosophy of mirroring how modern JavaScript learners actually first encounter the language in the wild. No reviewers described him as dry or hard to follow; the occasional criticism targets the course's depth or the complexity of the chosen teaching sequence, not the instructor's delivery itself.

Access to this course requires a LinkedIn Learning subscription ($39.99/month or $239.88/year), which unlocks the entire 21,000-course library. Multiple independent platform reviews note that the subscription price is reasonable if you are actively consuming multiple courses, but feels expensive for a single course. Critics on BitDegree and Career Sidekick note that some technically equivalent content exists on free platforms. For learners whose employer or university provides LinkedIn Learning access at no personal cost — a common arrangement — the value equation shifts strongly in favour of the course. The certificate, while not accredited, is displayable on a LinkedIn profile and is noted by several reviewers as a practical career visibility benefit.

The course includes mini-projects and interactive code challenges powered by CoderPad with real-time feedback, which reviewers describe as more engaging than passive video learning. However, multiple platform-level reviews of LinkedIn Learning note that technical courses "lack in-depth projects" and that the practice elements "do not go far enough for those seeking comprehensive understanding." One LinkedIn Learning reviewer noted the course is "a very VERY dense course" but the practice elements are limited relative to the volume of concepts introduced. The course does not include a capstone or portfolio-ready project, which distinguishes it from longer Udemy alternatives.

The course covers genuinely modern JavaScript — ES6+ syntax, DOM APIs, event-driven programming, and the underlying concepts used in frameworks like React and Vue. Nick Simson's blog review specifically notes that Morten's object-first teaching sequence acknowledges that modern learners encounter JavaScript through frameworks before mastering fundamentals, making the course sequencing more industry-realistic than traditional textbook approaches. The limitation is scope: at 6 hours, the course provides a strong foundation but stops well short of async JavaScript, Node.js, testing, TypeScript, or the deployment patterns required for professional work. Most reviewers position it as a starting point requiring significant follow-up rather than a job-ready course.

v6 is rebuilt around React 19 — render modes, React Server Components both from scratch and inside Next.js, transitions, optimistic and deferred values. Reviewers praise the "under the hood" RSC explanation. The honest caveat is that hooks, TypeScript and Redux content from older versions has been narrowed in favour of the RSC and performance focus.

Brian Holt is the single most consistently praised element across nine years of Hacker News mentions and official testimonials. Learners with one to three years of React experience still call the teaching "fun", "interactive" and clear. Official course rating sits at 4.7 stars.

Requires a Frontend Masters subscription ($39/month or $390/year). At a 6h22m runtime this single course is only worth the price if you pair it with the wider catalog or complete it inside one billing month. Less competitive against the free React docs if you want one course alone.

Unlike the project-based Complete Intro, the Intermediate course is modular — unrelated concepts taught as standalone lessons (RSCs from scratch, RSCs with Next.js, performance demos). Reviewers find the build-from-scratch RSC segment genuinely illuminating, but there is no single cohesive app to carry away as a portfolio artefact.

The RSC and performance material maps directly onto what teams are shipping with Next.js App Router in 2026. Learners specifically credit it with demystifying what Next.js is doing under the hood — transferable knowledge rather than tutorial-only skills.
