With a book named "Master JavaScript Design Patterns", I was expecting
|
|
|
|
|
something about some JavaScript common patterns, like subscribing and
|
|
|
|
|
generating events, proper way of transversing structures and such.
|
|
|
|
|
|
|
|
|
|
But nope.
|
|
|
|
|
|
|
|
|
|
The book starts with the classical design patterns from the Gang of Four,
|
|
|
|
|
which doesn't seem so bad if the book was named "Learning Design Patterns with
|
|
|
|
|
JavaScript", in a way to make learning the design patterns more streamlined
|
|
|
|
|
for people who already know JavaScript. But, then again, things fall apart,
|
|
|
|
|
with the Observer pattern being designed with a list of callbacks in a
|
|
|
|
|
structured, instead of creating a real event -- something, again, really
|
|
|
|
|
common in JavaScript.
|
|
|
|
|
|
|
|
|
|
Not only that, but some stuff seems really off. Like explaining lazy
|
|
|
|
|
evaluation -- something only ES6 has -- with... lists. Yup, lazy evaluation,
|
|
|
|
|
for the book, means adding things in a list only when you need to remove
|
|
|
|
|
things from the list. It would make so much more sense if the author jumped
|
|
|
|
|
into the ES6 bandwagon for this and explained the "yield" command... but no,
|
|
|
|
|
he had to write some lazy text.
|
|
|
|
|
|
|
|
|
|
The fact that all examples are based on Game of Thrones -- with all being
|
|
|
|
|
based on things that happen in Westeros -- don't make it funny or interesting.
|
|
|
|
|
Worse, none of the examples are related, so the author just keeps jumping
|
|
|
|
|
between weird scenarios to explain the "patterns".
|
|
|
|
|
|
|
|
|
|
Even when you throw the JavaScript away and decide to read it to learn some
|
|
|
|
|
design patterns, you waste your time. Some designs, mostly the MV*, are
|
|
|
|
|
hastily described and just superficially analyzed.
|
|
|
|
|
|
|
|
|
|
It really starts a bit off -- again, if it was "Learning Design Patterns with
|
|
|
|
|
JavaScript", it would be almost perfect -- and then goes downhill by some lazy
|
|
|
|
|
writing and wrong assumptions.
