I think the book has a really high virality factor. I was able to do a few posts on reddit, and people would like and share it. It's that whole "product market fit" thing. If you have a good product that people need or want, then marketing is pretty easy, and word of mouth (whether online or in real life) drives way more sales than anything else.
Making money from books is hard in general. OP found a great niche and amazing market fit. For frontend books, you will have tough competition not just from other similar books, but also bootcamps, free tutorials etc.
