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"

Requires or disallows a whitespace (space or tab) beginning a comment (spaced-comment)

Some style guides require or disallow a whitespace immediately after the initial // or /* of a comment. Whitespace after the // or /* makes it easier to read text in comments. On the other hand, commenting out code is easier without having to put a whitespace right after the // or /*.

Rule Details

This rule will enforce consistency of spacing after the start of a comment // or /*. It also provides several exceptions for various documentation styles.

Options

The rule takes two options.

• The first is a string which be either "always" or "never". The default is "always".

  • If "always" then the // or /* must be followed by at least one whitespace.
  • If "never" then there should be no whitespace following.

• This rule can also take a 2nd option, an object with any of the following keys: "exceptions" and "markers".

  • The "exceptions" value is an array of string patterns which are considered exceptions to the rule. Please note that exceptions are ignored if the first argument is "never".

  "spaced-comment": ["error", "always", { "exceptions": ["-", "+"] }]

  • The "markers" value is an array of string patterns which are considered markers for docblock-style comments, such as an additional /, used to denote documentation read by doxygen, vsdoc, etc. which must have additional characters. The "markers" array will apply regardless of the value of the first argument, e.g. "always" or "never".

  "spaced-comment": ["error", "always", { "markers": ["/"] }]

The difference between a marker and an exception is that a marker only appears at the beginning of the comment whereas exceptions can occur anywhere in the comment string.

You can also define separate exceptions and markers for block and line comments. The "block" object can have an additional key "balanced", a boolean that specifies if inline block comments should have balanced spacing. The default value is false.

• If "balanced": true and "always" then the /* must be followed by at least one whitespace, and the */ must be preceded by at least one whitespace.

• If "balanced": true and "never" then there should be no whitespace following /* or preceding */.

• If "balanced": false then balanced whitespace is not enforced.

"spaced-comment": ["error", "always", {
    "line": {
        "markers": ["/"],
        "exceptions": ["-", "+"]
    },
    "block": {
        "markers": ["!"],
        "exceptions": ["*"],
        "balanced": true
    }
}]

always

Examples of incorrect code for this rule with the "always" option:

/*eslint spaced-comment: ["error", "always"]*/

//This is a comment with no whitespace at the beginning

/*This is a comment with no whitespace at the beginning */

/* eslint spaced-comment: ["error", "always", { "block": { "balanced": true } }] */
/* This is a comment with whitespace at the beginning but not the end*/

Examples of correct code for this rule with the "always" option:

/* eslint spaced-comment: ["error", "always"] */

/* This is a comment with a whitespace at the beginning */

/*

/*

/* eslint spaced-comment: ["error", "always"] */

never

Examples of incorrect code for this rule with the "never" option:

/*eslint spaced-comment: ["error", "never"]*/

// This is a comment with a whitespace at the beginning

/* This is a comment with a whitespace at the beginning */

/* \nThis is a comment with a whitespace at the beginning */

/*eslint spaced-comment: ["error", "never", { "block": { "balanced": true } }]*/
/*This is a comment with whitespace at the end */

Examples of correct code for this rule with the "never" option:

/*eslint spaced-comment: ["error", "never"]*/

/*This is a comment with no whitespace at the beginning */

/*eslint spaced-comment: ["error", "never"]*/

/**

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 94.

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.
