In a word: FIRST! https://www.code4it.dev/cleancodetips/avoid-subtle-duplication/ Tue, 28 Jun 2022 00:00:00 +0000 https://www.code4it.dev/cleancodetips/avoid-subtle-duplication/ Duplication is not only about lines of code, but also about data usage and meaning. You should avoid that kind of duplication. https://www.code4it.dev/cleancodetips/tests-should-be-readable-too/ Tue, 24 May 2022 00:00:00 +0000 https://www.code4it.dev/cleancodetips/tests-should-be-readable-too/ Should you write your tests with the same care you write the production code? Of course you should! But what does it mean? https://www.code4it.dev/cleancodetips/too-many-imports/ Tue, 19 Apr 2022 00:00:00 +0000 https://www.code4it.dev/cleancodetips/too-many-imports/ Having too many ‘using’s, or imports, is a good indicator that your class does too many things. You should work to reduce the number of dependencies of a class. https://www.code4it.dev/cleancodetips/good-comments/ Tue, 22 Mar 2022 00:00:00 +0000 https://www.code4it.dev/cleancodetips/good-comments/ Is it true that we should always avoid comments in our code?

They must be correct. The second one? They must be readable. The AAA pattern helps you write better tests. https://www.code4it.dev/cleancodetips/avoid-mental-mappings/ Tue, 25 Jan 2022 00:00:00 +0000 https://www.code4it.dev/cleancodetips/avoid-mental-mappings/ Mental mappings are a good way to write shorter code that you, and only you, can understand. Prefer clarity over brevity! https://www.code4it.dev/cleancodetips/consistent-of-parameters/ Tue, 30 Nov 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/consistent-of-parameters/ Following a coherent standard, even for parameters order, helps developers when writing and, even more, reading code. How to do that? https://www.code4it.dev/cleancodetips/too-many-method-arguments/ Tue, 02 Nov 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/too-many-method-arguments/ When a function has too many parameters, it’s clear that something is wrong. But… why? What are the consequences of having too many parameters? https://www.code4it.dev/cleancodetips/use-same-name-for-same-concept/ Tue, 05 Oct 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/use-same-name-for-same-concept/ Smaller functions help us write better code, but have also a nice side effect: they help us to understand where an exception was thrown. Let’s see how! https://www.code4it.dev/cleancodetips/smaller-functions-smarter-exceptions/ Tue, 17 Aug 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/smaller-functions-smarter-exceptions/ Smaller functions help us write better code, but have also a nice side effect: they help us to understand where an exception was thrown.

What to choose? https://www.code4it.dev/cleancodetips/use-pronounceable-names/ Tue, 20 Jul 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/use-pronounceable-names/ Two of the operations you often do with your code is to discuss it, or perform a search over it. So using good names will help in both situations. https://www.code4it.dev/cleancodetips/principle-of-least-surprise/ Tue, 22 Jun 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/principle-of-least-surprise/ The Principle of Least Surprise is a simple principle that helps you writing clear, obvious code: this helps other developers foresee what a component does without worrying of unexpected behaviors. https://www.code4it.dev/cleancodetips/choose-meaningful-names/ Tue, 25 May 2021 00:00:00 +0000 https://www.code4it.dev/cleancodetips/choose-meaningful-names/ Choosing meaningful names takes time! Time spent finding good names is time saved trying to figure out what you meant. https://www.code4it.dev/blog/clean-code-tests/ Tue, 23 Mar 2021 00:00:00 +0000 https://www.code4it.dev/blog/clean-code-tests/ Tests are as important as production code. Well, they are even more important! So writing them well brings lots of benefits to your projects. https://www.code4it.dev/blog/clean-code-error-handling/ Tue, 15 Dec 2020 00:00:00 +0000 https://www.code4it.dev/blog/clean-code-error-handling/ The way you handle errors on your code can have a huge impact on the maintainability of your projects. Don’t underestimate the power of clean error handling. https://www.code4it.dev/blog/clean-code-abstraction-and-objects/ Tue, 20 Oct 2020 00:00:00 +0000 https://www.code4it.dev/blog/clean-code-abstraction-and-objects/ Are Getters and Setters the correct way to think of abstraction?

And, in the OOP world, how can you define objects? https://www.code4it.dev/blog/clean-code-comments-and-formatting/ Tue, 18 Aug 2020 00:00:00 +0000 https://www.code4it.dev/blog/clean-code-comments-and-formatting/ Are all comments bad? When they are necessary? Why formatting is so important? Writing clean code does not only refer to the executed code, but also to everything around. https://www.code4it.dev/blog/clean-code-names-and-functions/ Tue, 21 Jul 2020 00:00:00 +0000 https://www.code4it.dev/blog/clean-code-names-and-functions/ I don’t have to tell you why you need to write clean code.
