How do you maintain a bad code?
Strategies for Fixing Bad Code
- Have the original author rewrite the bad code. You can, of course, simply to ask the person who wrote the bad code to fix it.
- Rewrite the bad code yourself.
- Reject the bad code.
- Keep the bad code, but note its badness (and fix it later).
- Destroy everything and start from scratch.
What is poorly written code?
The definition is: A bad code is when a programmer or coder do program to get things done faster without thinking much about future changes and ignoring the possibility of other developers touching the code. Hard to read and understand: The first characteristic of bad code is that nobody else understands it fast.
What should good code look like?
Good code is well-organized. Data and operations in classes fit together. There aren’t extraneous dependencies between classes. It does not look like “spaghetti”.
How does a good code look like?
Good code uses meaningful naming conventions for all but the most transient of objects. the name of something is informative about when and how to use the object. Good code is well-tested. Tests serve as an executable specification of the code and examples of its use.
What’s the best way to maintain a codebase?
This basic rule is the most simple secret for maintaining an existing codebase. One of the most important factors influencing the maintainability of code is its readability. The more readable the code is, the easier it is to maintain that code. The more cryptic and difficult to understand code is, the more difficult it is to maintain.
What’s the best way to maintain your code?
They’ve spent enough time looking at someone else’s code—or their own—and trying to maintain it that they know the best code they can write is the code that is the most maintainable. One secret to being great at maintaining code is the Boy Scout Rule. This rule originates from the Boy Scouts of America who emphasize a simple rule for camping:
When do you need a programmer to understand your code?
Every time a programmer is trying to understand some workflow passing through your code so they in turn can add a new feature, modify an existing one, or troubleshoot a bug, they are going to need to understand what your code is doing.
How do you dive into large code bases?
Approaches you might consider: Try to find out what the code is supposed to do, in business terms. Read all the documentation that exists, no matter how bad it is. Talk to anyone who might know something about the code. Step through the code in the debugger. Introduce small changes and see what breaks.
