I'm writing a 3rd edition of
Writing is a lot of work, and I know a lot of people appreciate this
work, so I hope some of you are interested in chipping in some money
to help pay for my time.

a second edition in 2014.
That second edition is three years old now, which in terms
of Web technology is ancient.
Each of these versions has been publicly available
That site attracts over a hundred thousand unique visitors per month,
so it is probably reasonable to say that this book has taught over a
million people at least some programming.
Because I'd hate for the book to go out of date to the point where
it is no longer a useful resource, I've started work on a third

ES2015), which is a major update to the language. We're all
writing let instead of var now, and a book that
continues to write var is starting to look a bit out of
The idiomatic way of doing a lot of things has changed with
ECMAScript 6, and teaching it that way from the ground up will require
a thorough pass over the entire text, as well as a bunch of new
For example, the way we're doing asynchronous programming has
gotten much more pleasant with promises and async functions.
I'm planning a new chapter dedicated to that.
And browsers moved forward, too. Not quite as much as they did
between the first and second editions, but many things got easier. Due
to components and functional-reactive-style finally making it into the
mainstream, we've started writing web apps in a very different way. I
want to let some of those ideas flow into the web-programming examples
in the book.
And finally, I've done a lot of programming in the past three years
(building ProseMirror, among
other things), and I want to integrate various new insights into the
text. I'll rewrite or cut some sections that I don't like anymore, and
simplify examples that are
I estimate that I'll probably be busy with this for the next three
months. When it's done, the new edition will become the main one on
the website. In the meantime,
repository for the book remains open, so you can see what I'm
doing. No Starch, my
publisher, is interested in helping edit the book and publishing it in
paper form again. Finalizing the copy editing and layout, and getting
the actual book printed, will probably take somewhat longer.
Perks and Conditions
This crowd-funding campaign is ran in an open-ended way—even if I
don't reach my goal, the book will come into existence in some form,
and I keep the money raised. The campaign ends when the online book is
published, which I'm aiming to do in December 2017.

If more than 10,000 € is raised, I'll spend at least 2500 € to
commission an illustrator to do some new art for the
book—illustrations, maybe a new cover, depending on who I end up
working with and the kind of thing they specialize in.
