    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

          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 96.

          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.

            Limit Cyclomatic Complexity (complexity)

            Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.

            function a(x) {
                if (true) {
                    return x; // 1st path
                } else if (false) {
                    return x+1; // 2nd path
                } else {
                    return 4; // 3rd path
                }
            }

            Rule Details

            This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20).

            Examples of incorrect code for a maximum of 2:

            /*eslint complexity: ["error", 2]*/
            
            function a(x) {
                if (true) {
                    return x;
                } else if (false) {
                    return x+1;
                } else {
                    return 4; // 3rd path
                }
            }

            Examples of correct code for a maximum of 2:

            /*eslint complexity: ["error", 2]*/
            
            function a(x) {

                    return x;
                } else {
                    return 4;
                }
            }

            Options

            Optionally, you may specify a max object property:

            "complexity": ["error", 2]

            is equivalent to

            "complexity": ["error", { "max": 2 }]

            Deprecated: the object property maximum is deprecated. Please use the property max instead.

            When Not To Use It

            If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.

                Limit Cyclomatic Complexity (complexity)

                Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.

                function a(x) {
                    if (true) {
                        return x; // 1st path

                        return x+1; // 2nd path

                    }
                }

                Rule Details

                This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20).

                Examples of incorrect code for a maximum of 2:

                    }
                }

                Options

                Optionally, you may specify a max object property:

                "complexity": ["error", 2]

                is equivalent to

                "complexity": ["error", { "max": 2 }]

                Deprecated: the object property maximum is deprecated. Please use the property max instead.

                When Not To Use It

                If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.

                  Limit Cyclomatic Complexity (complexity)

                  Cyclomatic complexity measures the number of linearly independent paths through a program's source code. This rule allows setting a cyclomatic complexity threshold.

                  function a(x) {
                      if (true) {
                          return x; // 1st path
                      } else if (false) {
                          return x+1; // 2nd path
                      } else {
                          return 4; // 3rd path
                      }
                  }

                  Rule Details

                  This rule is aimed at reducing code complexity by capping the amount of cyclomatic complexity allowed in a program. As such, it will warn when the cyclomatic complexity crosses the configured threshold (default is 20).

                  Examples of incorrect code for a maximum of 2:

                  /*eslint complexity: ["error", 2]*/
                  
                  function a(x) {
                      if (true) {
                          return x;
                      } else if (false) {
                          return x+1;
                      } else {
                          return 4; // 3rd path
                      }
                  }

                  Examples of correct code for a maximum of 2:

                  /*eslint complexity: ["error", 2]*/
                  
                  function a(x) {
                      if (true) {
                          return x;
                      } else {
                          return 4;
                      }
                  }

                  Options

                  Optionally, you may specify a max object property:

                  "complexity": ["error", 2]

                  is equivalent to

                  "complexity": ["error", { "max": 2 }]

                  Deprecated: the object property maximum is deprecated. Please use the property max instead.

                  When Not To Use It

                  If you can't determine an appropriate complexity limit for your code, then it's best to disable this rule.
