* (-) Some phrase constructions are a bit hard to read. Maybe it's because I'm
not a native English speaker, but some phrases are akin to "my beautiful
nature photos", which you can read in different ways ("my beautiful
photos of nature", "my photos of beautiful nature") and I had to backtrack
and read the whole thing again.
* (-) Code is a mess. Long listings with no separation of concerns. I mean,
ok, you can use lambdas for simpler functions, but when you keep piling
lambdas over lambdas, things get a bit out of hand. Trying to explain
some functionality in a 200 line function is not actually helpful.

* (-) The ePub version seriously need another check. Some code listings are
pure text, so it follows the user font size; but other are
screenshots/images of code, which get way out of hand, as some listings
had fonts that where 1/5 of the font I use to read (yes, I use a large
font, I'm reading at night without my glasses, but the point remains).

how to do things with Sodium, the authors library. Instead of focusing on
how to build your own FRP system, using Sodium as reference, the books

* (--) The authors show some weird prejudices against TDD. For example, they
say that FRP doesn't require TDD and that using TDD is actually _harmful_
for FRP, "unless you test logic". I mean, seriously? What do you think TDD
is about? Lines of code? TDD says that "tests should validate behaviors,
not implementation" and I'm wondering why the authors are so reticent
against TDD when their concept of TDD seems completely out of place.

frameworks, the authors decided to focus more on "why this framework
is not pure FRP, while Sodium is" instead of, again, focusing on the
concepts of FRP itself. "FRP says so and so, you can build this with
framework X using that and that" is a good way to do it; "FRP says so and
so, framework X do this which is not what the FRP says, so framework X is
not FRP, but Sodium is!" is a dickish way to downplay other frameworks.
Also, it's weird that every time Sodium breaks some FRP rule (rules that
Not only that, but every time Sodium break some FRP rule (rules that
the authors themselves keep listing), they put a long explanation on why
it's ok to break the rule there, saying that it's ok that Sodium breaks
it.
it's ok for you to break the rule there when using Sodium, but Sodium,
although requiring you to break some FRP rule, is actually a pure-FRP
framework, and not those pesky other frameworks that are not pure-FRP
frameworks.
Honestly, I read the book and I still don't understand FRP; all I got was some
concepts for a Sodium framework.

in this post. :p
[^2]: That's surprise.
[^3]: That's confusion.
