JavaScript Grammar

I reckon [JavaScript Grammar](https://medium.com/@js_tut/get-javascript-grammar-for-free-9ea523e3ba1e?sk=e06a5101e0a80b7576ce60dd998a216c) is going to become _the_ first JavaScript book to get the nuts and bolts of JavaScript, insofar as it starts simple while going into details, and using many diagrams to communicate concepts. It is going to be released on the 27th of March, which gives a small window to get a free copy. There are not that many good useful technical books around, but I am guessing this will be one of them.

I suspect it should cover all the details necessary for fully understanding the Elm in JavaScript tutorials, but I will have to have looksee!

Start by reviewing the linked JavaScript Grammar book and the surrounding issue context in this repository. The issue does not identify a file, test, or requested change, so first establish whether the recommendation should become repository content; done would require a clearly defined contribution and an agreed location.
