    Cognitive Complexity

    Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

    A method's cognitive complexity is based on a few simple rules:

    • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
    • Code is considered more complex for each "break in the linear flow of the code"
    • Code is considered more complex when "flow breaking structures are nested"

                                Cognitive Complexity

                                Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

                                A method's cognitive complexity is based on a few simple rules:

                                • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
                                • Code is considered more complex for each "break in the linear flow of the code"
                                • Code is considered more complex when "flow breaking structures are nested"

                                Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

                                Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

                                When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

                                Duplicated Code

                                Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

                                Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

                                When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

                                Tuning

                                This issue has a mass of 36.

                                We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

                                The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

                                If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

                                See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.
