alt Hacker NewsThey aren't book-length chapters. E.g. https://gibbok.github.io/typescript-book/book/strictnullchec... is one paragraph, https://gibbok.github.io/typescript-book/book/void-type/ is 1 sentence plus 1 3-line example. Near all of those "chapters" seem to be bit more than that. 1~2 paragraphs plus 1~2 code examples.
you're not meant to scroll ahead, the intention is to create a time sink in each chapter. I figured this out after reading the first chapter forever, then I was like "wait a second this is the concise book? how can I read the introduction forever?"
