JavaScript is the only language that runs in the browser, which makes it unavoidable in front-end work and on the web generally. Udemy carries thousands of courses on it, and the quality spread is enormous. This shortlist covers different stages: from your first "Hello, world" to algorithms the week before an interview.
How these courses were selected
The same three criteria as in the Python course shortlist:
- Rating and review volume — at least 4.5 stars across tens of thousands of ratings. A small sample proves nothing.
- Freshness — reissued or extended within the last year or two. The language moves slowly; the ecosystem and its practices don't.
- Practice — a curriculum built around projects you keep in your portfolio.
A full start: from zero to your first projects
The Complete JavaScript Course: From Zero to Expert!
Jonas Schmedtmann's course is the most popular JavaScript starting point on Udemy. Over 60 hours: syntax, the DOM, asynchrony, modules, tooling. Half the runtime is spent building real applications alongside the instructor and then extending them yourself.
Who it's for
People starting from nothing who want one big course instead of ten small ones. The English is clear, the pace is moderate, and subtitles are available.
Modern JavaScript From The Beginning
Brad Traversy's course is tighter and more demanding. Less talking, more code: the language, DOM work, HTTP requests, asynchrony, OOP, and several small applications built without any framework.
Who it's for
Anyone with experience in another language who wants a fast entry into JavaScript without being told what a variable is.
The Web Developer Bootcamp
Colt Steele's course covers not just JavaScript but everything around it: HTML, CSS, Node.js, databases. It isn't a course about a language — it's a course about the job of a web developer, with JavaScript at the center.
Who it's for
People who don't want to "learn a language" so much as build and deploy a complete application for the first time.
Going deeper: understanding how it works
JavaScript: Understanding the Weird Parts
Anthony Alicea's course is about the machinery: execution context, closures, prototypes, this, hoisting. It's not a starting course — it explains why the code you already write behaves the way it does.
Who it's for
Anyone a few months into JavaScript who keeps running into "magic". It removes the fear of a fundamentals interview.
JavaScript Algorithms and Data Structures Masterclass
Another Colt Steele course, this one on algorithmic preparation in JavaScript: complexity, sorting, trees, graphs, dynamic programming. It's the standard interview syllabus.
Who it's for
Anyone preparing for interviews at companies that ask algorithm questions. For someone building marketing pages, it's overkill.
Courses in other languages
If English is still in the way, Udemy has strong JavaScript courses in Russian and other languages. Screen them the same way: 4.5+ rating, tens of thousands of ratings, a recent update date, and a curriculum built on projects rather than a recital of the MDN reference.
Starting in your native language is perfectly fine. You'll need English in development eventually, but learning a language and a profession at the same time is harder than doing them in sequence.
Picking one course out of five
Don't buy two courses "to have them" — you'll finish neither. The logic is simple:
- Complete beginner to programming — The Complete JavaScript Course.
- Already program in another language — Modern JavaScript From The Beginning.
- Want the profession, not the language — The Web Developer Bootcamp.
- Know the language but don't understand it — Understanding the Weird Parts.
- Interviewing soon — the algorithms course.
The full vetting criteria for any course are in the checklist for choosing a Udemy course.
Buying the course when your card isn't accepted
Udemy doesn't take Russian-issued cards directly, but the course can still be bought officially — as a gift. Paste the course link into the form on the ForUdemy homepage, check the price, and pay by card, SBP, or cryptocurrency. The gift code arrives by email and the course stays in your library permanently. Every payment route is compared in the guide to paying for Udemy from Russia.
Don't pay the list price: Udemy promotions run nearly every week, and a course listed at $84.99 regularly sells for $13–15. How to time it is covered in Udemy sales and discounts.
Where to start today
- Pick one course from the list above and close the other tabs.
- Type the code by hand alongside the video — watching without typing doesn't work.
- After each section, give yourself a small assignment: change the instructor's project in a way they never demonstrated.
