If I had to define this book in a single word, I'd had to go with "unfocused".
|
|
|
|
|
|
|
|
|
|
Now, with that title, you'd expect to learn about the principles that drove
|
|
|
|
|
the design of things like "ReactJS". But it doesn't. This is not about
|
|
|
|
|
Reactive Programming. It's about ReactJS. And it's not about Reactive
|
|
|
|
|
Programming, it's about Reactive *Funcional* Programming.
|
|
|
|
|
|
|
|
|
|
Well, you'd still expect it to come with some conclusions about ReactJS,
|
|
|
|
|
right? Wrong again.
|
|
|
|
|
|
|
|
|
|
Most of the time you'll spend reading things that have absolutely no relation
|
|
|
|
|
with reactive programming, functional reactive programming or even ReactJS.
|
|
|
|
|
There is a long rant about C++ which ends with no conclusion at all and gives
|
|
|
|
|
no pointers on how it connects to the whole. There is another discussion about
|
|
|
|
|
INTERCAL which leads to nowhere -- maybe, except, the author's bank account
|
|
|
|
|
for the number of words.
|
|
|
|
|
|
|
|
|
|
At some point, the author finally discusses a bit of functional programming
|
|
|
|
|
talking about `map`, `filter` and `reduce`, but it goes nowhere from there and
|
|
|
|
|
a whole chapter with 10+ pages have a single paragraph about real, focused
|
|
|
|
|
talk about functional programming; the rest is just more rambling going to
|
|
|
|
|
nowhere.
|
|
|
|
|
|
|
|
|
|
If it was possible to run tests over the content of the book, the amount of
|
|
|
|
|
content out of a coverage on a BDD about Reactive Programming would point that
|
|
|
|
|
about 90% of it is never tested. It's content that talks absolutely *nothing*
|
|
|
|
|
about reactive programming, with large portions being repeated over and over
|
|
|
|
|
again (which makes me, once again, wonder why Packt pays for reviewers when
|
|
|
|
|
this kind of bullshit happens).
|
|
|
|
|
|
|
|
|
|
"This book is about ReactJS", the author says in the introduction, but there
|
|
|
|
|
are only 4 chapters about ReactJS, with terrible JavaScript and absolutely no
|
|
|
|
|
explanation on *why* things are being designed that way.
|
|
|
|
|
|
|
|
|
|
You want a review in a single phrase? Ok, that phrase would be "stay away from
|
|
|
|
|
this book".
