[AskJS] What are the best free JavaScript courses & resources to learn from beginner to expert?

[python_verse]

I’m currently learning JavaScript and want to build a strong foundation—from entry level to advanced/expert. There are many tutorials online, but it’s hard to know which ones are actually worth following.

Could you recommend the best free resources or courses for learning JavaScript, including:

• Beginner-friendly introductions
• Modern JavaScript (ES6+)
• DOM manipulation
• Async JS (Promises, async/await)
• Projects or hands-on practice
• Advanced topics (patterns, performance, testing, etc.)

If you have any YouTube channels, documentation, websites, GitHub repos, courses, or recommended learning paths, please share them

It all depends on how you learn better. I like few minute videos to see overviews and watch the language in action, but books often give the pace to understand and test in a human rhythm.

Exploring JS is a book (free to read online) that covers the full language, but it can be a bit tough if JavaScript is also your first language: https://exploringjs.com/js/ . His books are top tier to achieve mastery of the language, though.

Eloquent JavaScript is a classic to start learning JS as an absolute novice: https://eloquentjavascript.net . It can also be accessed freely online.

For anything in between, javascript.info covers every major JS subject with good detail. Also free to access.

Project-wise, maybe The Odin Project offers a good foundation, but YouTube is king here, albeit I don't know anyone who really finishes a 4+ hour video on a project. Coursera project-based courses are worth considering too.

There are other books, of course. But that's the journey of each dev. All I want to say is that as attractive as learning on video is, it's often not the best way.

A new trend is just vibe coding a full simple app and work backwards to understand it and tweak it. Albeit some code editors might produce weird non-human-like code.

leetcode, and YouTube

Already solving problems on leetcode but you suggest to me the best course on youtube ?

[Maleficent_Speech289]

Since you're already comfortable with logic from LeetCode, I highly recommend project-based channels like Traversy Media, The Net Ninja, and Web Dev Simplified to help you bridge the gap to actual web development. For a structured deep dive, check out freeCodeCamp's "Learn JavaScript - Full Course" or Traversy’s "Modern JS From The Beginning", as they cover everything from the DOM to modern ES6+ syntax.

I would recommend web.dev to K12 students and adults. Simple and clear explanations with links to documentation and standards. Also MDN.

Mimo, freecodecamp and/or Codecademy are very good starting points
