r/javascript on Reddit: Is mozilla mdn the most complete javascript documentation?
March 23, 2017 -
I'm looking to improve my javascript knowledges as much as possible. So far I've been learning form online courses, but I'm pretty sure some of them might not be as complete as I want. What I'm really searching is an online documentation that covers all the javascript language. So far I've found the mozilla online documentation, if you know something much better than that please like me the source, thank you!

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.
