    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"

        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:

                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.

                Require Guarding for-in (guard-for-in)

                Looping over objects with a for in loop will include properties that are inherited through the prototype chain. This behavior can lead to unexpected items in your for loop.

                for (key in foo) {
                    doSomething(key);
                }

                Note that simply checking foo.hasOwnProperty(key) is likely to cause an error in some cases; see [no-prototype-builtins](no-prototype-builtins.md).

                Rule Details

                This rule is aimed at preventing unexpected behavior that could arise from using a for in loop without filtering the results in the loop. As such, it will warn when for in loops do not filter their results with an if statement.

                Examples of incorrect code for this rule:

                /*eslint guard-for-in: "error"*/
                
                for (key in foo) {
                    doSomething(key);

                Require === and !== (eqeqeq)

                It is considered good practice to use the type-safe equality operators === and !== instead of their regular counterparts == and !=.

                The reason for this is that == and != do type coercion which follows the rather obscure Abstract Equality Comparison Algorithm. For instance, the following statements are all considered true:

                • [] == false
                • [] == ![]
                • 3 == "03"

                If one of those occurs in an innocent-looking statement such as a == b the actual problem is very difficult to spot.

                Rule Details

                This rule is aimed at eliminating the type-unsafe equality operators.

                Examples of incorrect code for this rule:

                /*eslint eqeqeq: "error"*/
                
                if (x == 42) { }
                
                if ("" == text) { }
                
                if (obj.getStuff() != undefined) { }

                The --fix option on the command line automatically fixes some problems reported by this rule. A problem is only fixed if one of the operands is a typeof expression, or if both operands are literals with the same type.

                Options

                always

                The "always" option (default) enforces the use of === and !== in every situation (except when you opt-in to more specific handling of null [see below]).

                Examples of incorrect code for the "always" option:

                /*eslint eqeqeq: ["error", "always"]*/
                
                a == b
                foo == true
                bananas != 1
                value == undefined
                typeof foo == 'undefined'
                'hello' != 'world'
                0 == 0
                true == true
                foo == null

                Examples of correct code for the "always" option:

                /*eslint eqeqeq: ["error", "always"]*/
                
                a === b
                foo === true
                bananas !== 1
                value === undefined
                typeof foo === 'undefined'
                'hello' !== 'world'
                0 === 0
                true === true
                foo === null

                This rule optionally takes a second argument, which should be an object with the following supported properties:

                • "null": Customize how this rule treats null literals. Possible values:
                  • always (default) - Always use === or !==.
                  • never - Never use === or !== with null.
                  • ignore - Do not apply this rule to null.

                smart

                The "smart" option enforces the use of === and !== except for these cases:

                • Comparing two literal values
                • Evaluating the value of typeof
                • Comparing against null

                Examples of incorrect code for the "smart" option:

                /*eslint eqeqeq: ["error", "smart"]*/
                
                // comparing two variables requires ===
                a == b
                
                // only one side is a literal
                foo == true
                bananas != 1
                
                // comparing to undefined requires ===
                value == undefined

                Examples of correct code for the "smart" option:

                /*eslint eqeqeq: ["error", "smart"]*/
                
                typeof foo == 'undefined'
                'hello' != 'world'
                0 == 0
                true == true
                foo == null

                allow-null

                Deprecated: Instead of using this option use "always" and pass a "null" option property with value "ignore". This will tell eslint to always enforce strict equality except when comparing with the null literal.

                ["error", "always", {"null": "ignore"}]

                When Not To Use It

                If you don't want to enforce a style for using equality operators, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/

                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 79.

                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.

                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 65.

                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.
