JavaScript Essential Training vs Complete Intro to SQL & PostgreSQL

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.

The course packs a substantial curriculum into 7 hours and 20 minutes, covering everything from database creation and basic CRUD operations to advanced topics including window functions, self joins, materialized views, transactions, and query performance analysis using EXPLAIN. The curriculum progresses logically, starting with fundamentals before building toward complex relational modeling — many-to-many relationships, foreign key constraints, and JSONB handling for semi-structured data. A distinguishing strength is the integration of Node.js exercises throughout, which connect raw SQL concepts to actual application development patterns. Reviewers consistently note that this practical framing — writing SQL in the context of a real backend app — sets the course apart from purely academic treatments of the language. The course materials are open-source (Apache 2.0 for code, CC-BY-NC-4.0 for lessons) and available at sql.holt.courses, which allows learners to revisit content after their Frontend Masters subscription lapses. The GitHub repository (442 stars, 68 forks as of mid-2026) also reflects active community engagement with the material. The one consistent criticism is scope relative to the "complete" label: one independent blogger (mattbatman.com) benchmarked Holt's similar SQLite course against Stephen Grider's 15+ hour Udemy offerings and found the depth lighter than the name implies. For a developer-oriented introduction to SQL fundamentals, however, the coverage is solid and well-sequenced.

Brian Holt brings an unusually credible background to this course — over a decade of engineering at Netflix, Reddit, and LinkedIn before moving into product management roles at Databricks, Neon, Snowflake/Streamlit, Stripe, and Microsoft Azure. This is not a bootcamp instructor teaching theory; the course reflects the experience of someone who has designed and queried databases in high-traffic production environments. Student feedback on Frontend Masters consistently praises Holt's teaching clarity. Testimonials from his broader catalog describe him as explaining "core principles in a clear, structured, easy-to-understand way," making learning "truly enjoyable and highly effective," and — in one superlative case — calling him "my favorite teacher of all time." These ratings span multiple courses, suggesting a consistent instructional standard rather than a single strong effort. The SQL course specifically draws praise for Holt's ability to contextualize database concepts within real web application workflows. One reviewer with eight years of web development experience noted they had previously avoided databases out of anxiety but finished the course feeling "well equipped to build the things which I procrastinated on." This transformation from apprehension to confidence is a recurring theme in the feedback. No substantive negative feedback targeting Holt's teaching style appeared in the reviewed corpus. The few critical comments focus on course scope or depth, not on instructional quality.

The course is available exclusively through a Frontend Masters subscription, priced at approximately $39/month or $390/year, which unlocks access to the full library of 200+ courses. For developers who plan to use multiple Frontend Masters courses, this model offers exceptional value — the SQL course alone would justify a month's subscription, and the library includes courses on React, Node.js, TypeScript, CSS, and system design that together form a complete web development curriculum. The open-source course website (sql.holt.courses) provides the written lessons and exercises at no cost, which is a notable differentiator. A developer on a tight budget can follow the written material for free; the Frontend Masters subscription adds the video recording of Brian teaching live, which many learners prefer for pacing and comprehension. The value calculation is somewhat sensitive to use case. A developer who wants only this one course and has no interest in the broader Frontend Masters library might find the subscription-only model slightly inflexible compared to a one-time Udemy purchase. However, no reviewer in the corpus raised this as a complaint — the consensus is that the library model represents good value for professional developers investing in continued learning.

The course is structured around hands-on exercises rather than passive video consumption. The Node.js integration exercises are the most praised component — they allow students to write SQL queries inside a working backend application, bridging the gap between learning syntax and understanding how SQL fits into real project architecture. One reviewer specifically called out the ability to "play around a bit in a NodeJS app to see how all of these concepts look like when you develop an app" as a key differentiator from other SQL courses. This framing reflects a genuine pedagogical choice: the course is designed for application developers who need to understand how to integrate SQL into a codebase, not for database administrators who work with raw SQL tooling. The course also uses the Movie Database (a well-known sample dataset) for query performance exercises, which gives learners a realistic dataset with enough complexity to demonstrate indexing and optimization meaningfully. The pgAdmin section provides familiarity with a production-grade GUI tool alongside command-line usage. The main limitation is the absence of a larger capstone project. The course builds toward exercises per module rather than a single cohesive application built from start to finish, which some developers prefer for a more integrated learning experience.

PostgreSQL is one of the most widely deployed relational databases in the industry, used by companies including Apple, Instagram, Spotify, and Netflix. Learning SQL through PostgreSQL positions developers for immediate applicability in a large fraction of real production environments. The course covers topics that regularly arise in professional database work: query optimization with EXPLAIN, indexing strategies (B-tree, GiST, GIN), transactions and isolation levels, views and materialized views for performance, and JSONB for hybrid relational/document data models. These are not academic topics — they are the exact problems that come up when a web application starts handling real user loads. Independent bloggers who have reviewed or recommended the course emphasize that Brian Holt "teaches you to think in SQL" rather than just syntax, which is the quality that separates educational content that sticks from reference material that fades. A developer with this foundation can productively engage with Prisma, Drizzle, SQLAlchemy, or raw SQL in any production context. Reviewers with significant prior experience report that the course delivered new, immediately applicable knowledge rather than only reinforcing basics. The developer who described it as "a great refresher course for Postgres and laying down the foundation for ORM" was reflecting a common pattern in the feedback: the course works both as a first introduction and as a consolidating reference for developers who learned SQL piecemeal.
