SUMMARY
In this chapter we've seen how even seemingly
minor details, like picking a name for something, can have a great
impact on the code quality. We've discussed several techniques for
choosing names, achieving simplicity, staying focused, and making
your code intent-revealing. The benefit to practicing these
techiques is code that is simple, understandable, and
maintainable.
Sooner or later, someone will read our code. We will ourselves
reread our code, sometimes after a long absence. Any readers,
including us, will be hindered or thwarted by code that is awkward,
complex, obscure, or in the worst case, misleading.
Well-crafted, simple, clear, intent-revealing
code will speed us in our work instead. Such code also helps teach
readers how to program well. It teaches good solutions to problems,
and teaches how to express those solutions succinctly.
Learning to code with this clear intent is well
worth any programmer's effort.
