It’s heavy on computer science, but this is a fascinating endeavour. It’s a work-in-progress book that not only describes how browsers work, but invites you to code along too. At the end, you get a minimum viable web browser (and more knowledge than you ever wanted about how browsers work).
As a black box, the browser is either magical or frustrating (depending on whether it is working correctly or not!). But that also make a browser a pretty unusual piece of software, with unique challenges, interesting algorithms, and clever optimizations. Browsers are worth studying for the pure pleasure of it.

Best of all, I get to work with the super-smart developer who did all this.
