How do I know if my code is bad?

Uncle Bob defines bad code as code that has the following attributes:

1. Rigidity. This refers to code being difficult to change.
2. Fragility.
3. Immobility.
4. Viscosity.

What good code looks like?

In terms of design, “good code” looks orderly, with clear implemented patterns (whatever that pattern may be), and is structured in alignment with conventions rather than invented and for single-use solutions.

Why do programmers make mistakes?

Generally speaking, monotonous work creates breeding ground for mistakes (which speaks to why doing such work is a smell for programmers). But it goes beyond the most obvious as well. Feeling tired or distracted can lead to concentration lapse mistakes. Interruptions and attempts to multi-task do the same.

How do you not write code in spaghetti?

Tips on how to avoid spaghetti code

2. Make self-contained functions.
3. Split your files.
4. Use a consistent naming convention.
5. Use docstrings.
6. Implement tests.
7. Long variable, short variable…
8. Use comments!

Why is spaghetti code bad?

Spaghetti code is when the code you work with is unstructured by nature, tightly coupled, and contains an unnecessary amount of mental translation between reality and its representations. The issue with spaghetti code is that the lines composed for the software are not easy to mentally digest.

How do I get better at coding?

What is bad coding?

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.

What is bad code quality and why does it matter?

Poorly written code, i.e. bad code quality, is usually hidden from non-technical people. Furthermore, a high quality UI does not necessarily mean the underlying code is written well. Poor code quality can be an extremely expensive problem to fix.

How does high quality code avoid duplication?

High quality code avoids duplication by combining shared functionality into reusable pieces of code that can invoked whenever it is needed. This makes the code easier to read, and repairs or extensions only need to be applied in one place. In programming lingo, an “Exception” is a rare-event that should be handled differently in the code.

Why is there so much misunderstanding about the quality of Ui?

The main reason for this misunderstanding is: The UI is visible and tangible, and it is possible for non-technical people to gage whether it is built well. Poorly written code, i.e. bad code quality, is usually hidden from non-technical people. Furthermore, a high quality UI does not necessarily mean the underlying code is written well.

Why is it difficult to read code?

Difficult to read code is problematic for a lot of reasons. Identifying and correcting bugs takes longer, adding new functionality is more difficult and error-prone, and new developers will take much longer getting started. There are many factors that affect codes readability.
