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"

require constructor names to begin with a capital letter (new-cap)

The new operator in JavaScript creates a new instance of a particular type of object. That type of object is represented by a constructor function. Since constructor functions are just regular functions, the only defining characteristic is that new is being used as part of the call. Native JavaScript functions begin with an uppercase letter to distinguish those functions that are to be used as constructors from functions that are not. Many style guides recommend following this pattern to more easily determine which functions are to be used as constructors.

var friend = new Person();

Rule Details

This rule requires constructor names to begin with a capital letter. Certain built-in identifiers are exempt from this rule. These identifiers are:

• Array
• Boolean
• Date
• Error
• Function
• Number
• Object
• RegExp
• String
• Symbol

Examples of correct code for this rule:

/*eslint new-cap: "error"*/

function foo(arg) {
    return Boolean(arg);
}

Options

This rule has an object option:

• "newIsCap": true (default) requires all new operators to be called with uppercase-started functions.
• "newIsCap": false allows new operators to be called with lowercase-started or uppercase-started functions.
• "capIsNew": true (default) requires all uppercase-started functions to be called with new operators.
• "capIsNew": false allows uppercase-started functions to be called without new operators.
• "newIsCapExceptions" allows specified lowercase-started function names to be called with the new operator.
• "newIsCapExceptionPattern" allows any lowercase-started function names that match the specified regex pattern to be called with the new operator.
• "capIsNewExceptions" allows specified uppercase-started function names to be called without the new operator.
• "capIsNewExceptionPattern" allows any uppercase-started function names that match the specified regex pattern to be called without the new operator.
• "properties": true (default) enables checks on object properties
• "properties": false disables checks on object properties

enforce consistent spacing before and after keywords (keyword-spacing)

Keywords are syntax elements of JavaScript, such as function and if. These identifiers have special meaning to the language and so often appear in a different color in code editors. As an important part of the language, style guides often refer to the spacing that should be used around keywords. For example, you might have a style guide that says keywords should be always surrounded by spaces, which would mean if-else statements must look like this:

if (foo) {
    // ...
} else {
    // ...
}

Of course, you could also have a style guide that disallows spaces around keywords.

Rule Details

This rule enforces consistent spacing around keywords and keyword-like tokens: as (in module declarations), async (of async functions), await (of await expressions), break, case, catch, class, const, continue, debugger, default, delete, do, else, export, extends, finally, for, from (in module declarations), function, get (of getters), if, import, in, instanceof, let, new, of (in for-of statements), return, set (of setters), static, super, switch, this, throw, try, typeof, var, void, while, with, and yield. This rule is designed carefully not to conflict with other spacing rules: it does not apply to spacing where other rules report problems.

Options

This rule has an object option:

• "before": true (default) requires at least one space before keywords
• "before": false disallows spaces before keywords
• "after": true (default) requires at least one space after keywords
• "after": false disallows spaces after keywords
• "overrides" allows overriding spacing style for specified keywords

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 140.

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.
