JavaScript: The Hard Parts, v2 vs The Complete 2024 Web Development Bootcamp

Goes deep on the JavaScript runtime model — thread of execution, the call stack, closure, the event loop, Promises and prototypes/classes — across roughly 6.5 hours. Reviewers consistently say it explains how JavaScript works "under the hood" rather than just syntax.

Will Sentance (Codesmith founder) is the most-praised element. Learners cite his blackboard diagrams, the "backpack" analogy for closure, and a Socratic, audience-paced delivery. The same intense, repetitive style is the one thing a minority find tiring.

Requires a $39/month Frontend Masters subscription rather than a one-time purchase — strong value if you use the wider catalog, weaker if you only want this one course. The course is included in the standard subscription.

This is a conceptual, exercise-and-whiteboard course, not a project build. There is no portfolio-worthy capstone, which some learners miss. The exercises are effective for drilling mental models but produce no artefact.

The mental models — call stack, closure, the event loop, async behaviour — directly explain bugs developers hit daily. Experienced developers report the course clarified concepts they had used for years without fully understanding.

Broad full-stack scope (HTML, CSS, JS, React, Node, Express, MongoDB, EJS, basic deployment) — wider than Colt Steele because React is in the main course. A recurring 2025 critique flags outdated sections that tripped up a zero-experience beginner.

Repeatedly described as beginner-friendly — "gets a basic understanding of dev in your head". The shared brand with her 100 Days of Python and iOS bootcamps anchors her as one of the most-recommended Udemy instructors for absolute beginners.

Listed near $200 but routinely buyable for $10-$15 on Udemy sales — the same pattern the corpus reports for every popular Udemy course. Every recommender we tracked explicitly names the sale price; no one pays sticker.

Many small build-along projects (Dicee, Drum Kit, Simon, Tindog, Newsletter Signup, Blog) plus a React capstone. Strong for keeping beginners motivated, weaker on a single non-trivial portfolio piece compared to Colt Steele's YelpCamp.

Includes a React section in the main course (the headline difference vs Colt Steele) and a separate MERN course as a follow-on path that one 2024 HN job-seeker credits with landing them at a TypeScript/ Next.js shop. Modern tooling, TypeScript and testing are still gaps.
