JavaScript Essential Training vs Typescript: The Complete Developer's Guide

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.

Reviewers consistently praise the course for going well beyond basic TypeScript syntax into OOP, design patterns, generics, and decorators. The curriculum's treatment of composition vs. inheritance and building a custom front-end framework from scratch are repeatedly cited as standout segments that most competing courses skip entirely. Minor deductions come from occasional notes about third-party library version drift (Axios, Parcel) in older sections.

Stephen Grider is consistently described as having an innate ability to simplify complex topics using diagrams and clear progressions, making abstract TypeScript concepts concrete for learners. He deliberately avoids shortcuts and shows both a naive approach and a refactored version side by side, a teaching pattern that learners call "totally worth it." His engagement with the subject matter and willingness to explain the reasoning behind design choices earns very high marks across all sources.

At the typical Udemy sale price of $10–20 for 27 hours of expert-led instruction, reviewers uniformly consider it excellent value. One Reddit user noted it was "totally worth" picking up for around 10 euros with a Udemy deal, and multiple sources rank it the best TypeScript offering on Udemy relative to price. Lifetime access with updates (the course was last refreshed in February 2026) adds further long-term value.

Building a custom front-end framework from scratch, integrating TypeScript with React/Redux, and implementing decorators with Express are praised by learners as projects that make abstract concepts tangible and directly applicable to production codebases. One reviewer specifically said "I really appreciated building the custom front-end framework; it made complex concepts tangible." Some learners find the projects long and want more bite-sized exercises alongside the extended builds.

The course's explicit focus on how TypeScript behaves inside larger codebases and monorepos addresses a gap that many TypeScript learners hit in real jobs. Coverage of generics, decorators, and type narrowing in practical contexts is rated highly. However, a handful of reviewers note that a few integration sections reference slightly older tooling versions, requiring minor workarounds on current setups.
