There is a surprisingly wide area of coverage for something titled "Front-end Developer Handbook". I also like the way the content is presented (not the technology used).
The JS testing section is a good example. Pertinent summary of high level concepts before the fold. Additional content to read if you want to learn more.

Edit:
By technology, I mean using a SPA for docs is silly. Not surprised the mobile experience is poor because of that.
