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

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

          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) {

                  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.

            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 70.

            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.

              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/
