For 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

Learning 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

Is mozilla mdn the most complete javascript documentation?
I would definitely say yes. If you can't locate it on MDN, it's either 1) proprietary to a specific vendor (read: IE...) or 2) not yet at a proposal stage where it makes sense to document it and even in both of those instances, MDN almost always has the definitions anyway, along with good tutorials/examples for the given subject or API.

I just finished their React course. After struggling with JavaScript, I did a combination of an O’Reilly Head First book 2nd edition (with my library card online) and it was that and MDN that got me over the hump for front end. I personally find the React docs overly complicated. I was able to get the app to closely match their finished product with react and while I wouldn’t do it the same way if you are a detail nerd like me, you’ll love their in depth tutorials. With their Express tutorial they don’t expect you to be smart enough and know what to look for in the documentation. They also gave me enough info on accessibility to get cracking with that in React.

Sure! It may not have Redux, but, honestly if you’re just starting out and you know absolutely nothing, and you question your HTML, CSS, and JavaScript I can fully recommend starting with the MDN over LinkedIn Learning over any other paid source, at least to start. They also frequently update their content.

r/learnjavascript on Reddit: Learning JS through MDN Documentation?
March 12, 2022 -

Long story short, I once had a professor who encouraged us at the beginning of the semester to read over, study, and analyze the documentation for Java, of course "i had better things to do". Trying to get back into programming after time away from school, and was wondering if it really is efficient to learn Javascript by reading the documentation itself instead of sources like YouTube.

This guide talks about how to do resource management in JavaScript. Resource management is not exactly the same as memory management, which is a more advanced topic and usually handled automatically by JavaScript. Resource management is about managing resources that are not automatically cleaned up by JavaScript.
