I'm currently loving the draft of the book. I'm moderately well off with javascript, but I've never used typescript before so I'm working on figuring that out as well. In any case, it's a wonderful book with plenty of diagrams with explanations. Highly recommended! I've spent years dabbling with programming language as well as compiler/debugger/simulator design, so all of this is right up my alley. :)
