What are the most common anti-patterns in code quality, and how can you address them?

I agree that sometimes it is situational and sometimes unintentional but it is not good and in the long run it is going to harm in terms of maintenance and effort etc. In my words - Anti-patterns are like bad habits in coding that can harm the quality of your software. - Remember when you are in a hurry and fixing something quickly they might seem like quick fixes, but they often create more issues over time. - Avoid anti-patterns like God objects, spaghetti code, hard-coded values, and copy-paste coding

An anti-pattern, is a way of building software systems, that should scare you. It is not necessarily wrong, as the name may imply, it is just most-likely wrong. It is wrong in many situations. For example, business logic at the data layer, like in stored procedure, is typically considered an anti-pattern. However, if speed is paramount, it maybe the best pattern for the job.

- Anti-patterns make your code more complicated. If I say it as a life example it is like reading a messy book that's confusing and hard to understand. - They can create errors and problems in your code. - Fixing anti-patterns takes extra time and money. - In the long run, it is going to affect the system and business.

A pattern is an anti-pattern, precisely because it has detrimental effects on the system. The question is a bit circular. A pattern earns the title of an anti-pattern when it is detrimental, in many ways, in many situations. Continuing with the "business logic in stored procedure" for example, it makes that code harder to test, maybe harder to understand and change (hence more expensive to maintain), requires a skill that most developers writing business logic do not have (pl/sql or t-sql) etc

- Get your code checked by other developers. - Get your code audited by professional teams. - There are tools that can find code problems, use them. - Test your code to find issues caused by anti-patterns, such as slow performance or mistakes.

Rather simple. First, study and understand all kinds of patterns. Sadly, such knowledge is rare. You must be well familiar with as many patterns and their applications as possible. Understand the strengths and weaknesses of each. Understand good and bad applications of each. The bad applications, are basically anti-patterns. Then, and only then, study classic anti-patterns (web is full of them). Do that, and anti-patterns will stare at you from code, will stand out like a sore thumb

- The first and most important thing is to refactor the code. - Follow software development principles for development. - Divide your code into modules. - Take care of naming conventions. - Make your team aware of the "Clean Code".

Once you already have an anti-patter in your architecture, design or code, it is already kind of late. First, you will have to convince the author and the team that this is indeed an anti-pattern. This is very important. If the team is not convinced, you will fix one instance of the pattern, just to find it popping in all over the place. And since one of the biggest anti-pattern is to have inconsistency in patters, it maybe better to let it go, and look for a better team. If you get enough team members on board with your idea, then you must convince the client that the fix is worth the time Refactoring is not free. Then, simply fix it

- Educate yourself and your team and make a good plan before you start coding. - Communicate with your team and others involved in your project about plans and design.

Education, education, education. For my teams, I have a curriculum - a set of courses, books, ideas they have to master and I give a bit of time during work, and expect them to spend a lot of time outside of work. There are various ways to keep track of progress, I typically ask each member to "rate" the resources, thus indicating they went through it. Then I learn if they actually did in conversations. Any team member that is not educating, is marked for removal. There is nothing more toxic to a team, then to keep bad people on it.
