javascript.info is an excellent reference for the fundamentals of JS

[Javascript.info](https://javascript.info/) is both a very complete reference, and starts from the very basics, so is friendly to absolute beginners in Javascript. I suggest also that is a more friendly reference for required background knowledge than Crockford's "Javscript the Good Parts" and a better reference than Haverbeke's "Eloquent Javascript". Also it is the only beginner reference I have seen that mentions both debugging _and_ testing! It is as if I have seen a flying pig. After this, there can only be MDN!

The issue names javascript.info but no project file, test, or documentation entry point. First inspect the repository’s existing learning references and decide whether this recommendation has a defined place; done should mean the reference is added consistently with the project’s documentation structure.
