Names are everywhere in software. We name variables, functions, arguments, classes, and packages. Because we name things so often, we often do it carelessly. But a bad name can obscure intent and create bugs.
If you cannot purchase the EPUB, consider:
If you have two variables in the same scope, do not number them a1 and a2. This adds no semantic information. Similarly, avoid "noise words." A variable named theCustomer is no better than customer. Distinguish names in a way that their differences are clear. codigo limpo epub
Do not try to read a chapter on "Error Handling" in one sitting. Read for 20 minutes, then spend 10 minutes refactoring an old script you wrote using the rule you just learned.
Code is clean if it is easy to understand, easy to change, and reflects the author’s intent. The cost of messy code (“technical debt”) increases exponentially over time. Clean code is not a luxury but a professional necessity. Names are everywhere in software
Antes de falarmos sobre o formato, vamos relembrar o valor do conteúdo. "Código Limpo" não é um livro sobre sintaxe; é um livro sobre humanidade.
Uncle Bob argumenta que um código não é escrito apenas para máquinas. Ele é escrito para pessoas – seus colegas de equipe, seu eu do futuro e os mantenedores que virão depois de você. Um código limpo é: Do not try to read a chapter on
O livro está repleto de smells (maus cheiros) de código, heurísticas e estudos de caso. Ele ensina desde a nomenclatura correta de variáveis até o gerenciamento adequado de exceções e comentários.
It is a common misconception in software development that "clean code" is a luxury—a nice-to-have that gets sacrificed at the altar of deadlines. Managers often scream, "We need to release by Friday! We can clean it up later." But "later" never comes. This is the paradox of software development: the only way to go fast is to go well.
Bad code slows you down. It creates friction. Every new feature added to a messy codebase increases the "wreckage," making the next feature harder to implement. Eventually, the team's velocity grinds to a halt. The cost of bad code is not just technical; it is existential.
Clean Code is not just about making code work. It is about creating code that speaks to the reader, code that is easy to read, easy to change, and easy to maintain. This book is a guide to that discipline.
