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 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

before

} else {

for(;;);

while(true) {

When Not To Use It

If you don't want to enforce consistency on keyword spacing, then it's safe to disable this rule. Source: http://eslint.org/docs/rules/

    try {

        this.options =
            new responseOptions.Constructor().validate(constructorOptions);

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 55.

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.
