May 29, 2024For beginners, I strongly recommend the MDN (Mozilla) docs as a place to start!
MDN is a fantastic reference, especially when you want to dive deep into specific details. However, for most people just starting to learn, you don’t need to get into all the details right away. You can always come back to it once you’ve grasped the basics and are ready to explore topics in more depth. I’d recommend starting with FreeCodeCamp or The Odin Project and using MDN as a reference only when you need to dig deeper into a concept. More on reddit.com

October 2, 2024Learning JS through MDN Documentation?
MDN is a (excellent) reference, not a class or tutorial. Very different focus. If you want to look up how some bit of syntax works, MDN is an amazing resource. If you want to learn broader concepts, some sort of course or tutorial would be better. (And yes, MDN has some broader articles too, but that is not the focus of the page) More on reddit.com

Download it at https://mdn-downloads.s3-us-west-2.amazonaws.com/developer.mozilla.org.tar.gz
The "Downloading content" section of About MDN provides the above link (for a tarball download) along with guidance on other ways to access the MDN content, both as single pages and via third-party tools.
And others : don't mirror with wget & co, this is putting un-needed pressure on the website and hinders other users. At least make sure https://developer.mozilla.org/robots.txt (which asks for gentle throttling) is properly handled. Wget does not handle this for instance (http://savannah.gnu.org/bugs/?30999).

The JavaScript docs along with most of MDN's web reference pages are available on DevDocs.
The app is open source and can be run offline: https://github.com/Thibaut/devdocs
It's easy to set up and doesn't require scraping MDN.

Everytime I search the web for Javascript documentation, I mostly see tutorials, the one from Mozilla.

The ECMA-262 specification is the closest you'll get, but it's not exactly accessible. Mozilla's JavaScript docs are the most authoritative of the remaining options.

„As a standard it is called ECMA Script (ES for short), it was standarized by Ecma International (a non-profit organization whose members are organizations) under the document ECMA-262. So, the website of the specification is https://www.ecma-international.org/ecma-262/ . As a trademark, JavaScript is owned by Oracle Corporation. The website of the trademark currlently is https://developer.oracle.com/ar/javascript/ ( https://developer.oracle.com/ar/javascript/).” Source: https://www.quora.com/Whats-the-official-website-of-JavaScript
