    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 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

                                                        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).

                                                        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.

                                                        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).

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

                                                        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).

                                                        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).

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

                                                        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.

                                                        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).

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

                                                        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.

                                                        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.

                                                        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).

                                                        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.

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

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

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

                                                        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).

                                                        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.
