    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"

      enforce a maximum number of statements allowed in function blocks (max-statements)

      The max-statements rule allows you to specify the maximum number of statements allowed in a function.

      function foo() {
        var bar = 1; // one statement
        var baz = 2; // two statements
        var qux = 3; // three statements
      }

      Rule Details

      This rule enforces a maximum number of statements allowed in function blocks.

      Options

      This rule has a number or object option:

      • "max" (default 10) enforces a maximum number of statements allows in function blocks

      Deprecated: The object property maximum is deprecated; please use the object property max instead.

      This rule has an object option:

      • "ignoreTopLevelFunctions": true ignores top-level functions

      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

              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.

        Disallow Functions in Loops (no-loop-func)

        Writing functions within loops tends to result in errors due to the way the function creates a closure around the loop. For example:

        for (var i = 0; i < 10; i++) {
            funcs[i] = function() {
                return i;
            };
        }

        In this case, you would expect each function created within the loop to return a different number. In reality, each function returns 10, because that was the last value of i in the scope.

        let or const mitigate this problem.

        /*eslint-env es6*/
        
        for (let i = 0; i < 10; i++) {
            funcs[i] = function() {
                return i;
            };

        Unexpected trailing comma.

        require or disallow trailing commas (comma-dangle)

        Trailing commas in object literals are valid according to the ECMAScript 5 (and ECMAScript 3!) spec. However, IE8 (when not in IE8 document mode) and below will throw an error when it encounters trailing commas in JavaScript.

        var foo = {
            bar: "baz",
            qux: "quux",
        };

        Trailing commas simplify adding and removing items to objects and arrays, since only the lines you are modifying must be touched. Another argument in favor of trailing commas is that it improves the clarity of diffs when an item is added or removed from an object or array:

        Less clear:

        var foo = {
        -    bar: "baz",
        -    qux: "quux"
        +    bar: "baz"
         };

        More clear:

        var foo = {
             bar: "baz",
        -    qux: "quux",
         };

        Rule Details

        This rule enforces consistent use of trailing commas in object and array literals.

        Options

        This rule has a string option or an object option:

        {
            "comma-dangle": ["error", "never"],
            // or
            "comma-dangle": ["error", {
                "arrays": "never",
                "objects": "never",
                "imports": "never",
                "exports": "never",
                "functions": "ignore",
            }]
        }
        • "never" (default) disallows trailing commas
        • "always" requires trailing commas
        • "always-multiline" requires trailing commas when the last element or property is in a different line than the closing ] or } and disallows trailing commas when the last element or property is on the same line as the closing ] or }
        • "only-multiline" allows (but does not require) trailing commas when the last element or property is in a different line than the closing ] or } and disallows trailing commas when the last element or property is on the same line as the closing ] or }

        Trailing commas in function declarations and function calls are valid syntax since ECMAScript 2017; however, the string option does not check these situations for backwards compatibility.

        You can also use an object option to configure this rule for each type of syntax. Each of the following options can be set to "never", "always", "always-multiline", "only-multiline", or "ignore". The default for each option is "never" unless otherwise specified.

        • arrays is for array literals and array patterns of destructuring. (e.g. let [a,] = [1,];)
        • objects is for object literals and object patterns of destructuring. (e.g. let {a,} = {a: 1};)
        • imports is for import declarations of ES Modules. (e.g. import {a,} from "foo";)
        • exports is for export declarations of ES Modules. (e.g. export {a,};)
        • functions is for function declarations and function calls. (e.g. (function(a,){ })(b,);)
          functions is set to "ignore" by default for consistency with the string option.

        disallow variable redeclaration (no-redeclare)

        In JavaScript, it's possible to redeclare the same variable name using var. This can lead to confusion as to where the variable is actually declared and initialized.

        Rule Details

        This rule is aimed at eliminating variables that have multiple declarations in the same scope.

        Examples of incorrect code for this rule:

        /*eslint no-redeclare: "error"*/
        
        var a = 3;
        var a = 10;

        Examples of correct code for this rule:

        /*eslint no-redeclare: "error"*/
        
        var a = 3;
        // ...
        a = 10;

        Options

        This rule takes one optional argument, an object with a boolean property "builtinGlobals". It defaults to false. If set to true, this rule also checks redeclaration of built-in globals, such as Object, Array, Number...

        builtinGlobals

        Examples of incorrect code for the { "builtinGlobals": true } option:

        /*eslint no-redeclare: ["error", { "builtinGlobals": true }]*/
        
        var Object = 0;

        Examples of incorrect code for the { "builtinGlobals": true } option and the browser environment:

        /*eslint no-redeclare: ["error", { "builtinGlobals": true }]*/
        /*eslint-env browser*/
        
        var top = 0;

        The browser environment has many built-in global variables (for example, top). Some of built-in global variables cannot be redeclared. 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 83.

        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.
