How often do you hear people say things like this? "Our JavaScript
is a mess, but we're thinking about using [framework of the
month]." Like it or not, JavaScript is not going away. No matter
what framework or "compiles-to-js" language or library you use,
bugs and performance concerns will always be an issue if the
underlying quality of your JavaScript is poor. Rewrites, including
porting to the framework of the month, are terribly expensive and
unpredictable. The bugs won't magically go away, and can happily
reproduce themselves in a new context. To complicate things
further, features will get dropped, at least temporarily. The other
popular method of fixing your JS is playing "JavaScript Jenga,"
where each developer slowly and carefully takes their best guess at
how the out-of-control system can be altered to allow for new
features, hoping that this doesn't bring the whole stack of blocks
down. This book provides clear guidance on how best to avoid these
pathological approaches to writing JavaScript: Recognize you have a
problem with your JavaScript quality. Forgive the code you have
now, and the developers who made it. Learn repeatable, memorable,
and time-saving refactoring techniques. Apply these techniques as
you work, fixing things along the way. Internalize these
techniques, and avoid writing as much problematic code to begin
with. Bad code doesn't have to stay that way. And making it better
doesn't have to be intimidating or unreasonably expensive.
