    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"

                    disallow the use of console (no-console)

                    In JavaScript that is designed to be executed in the browser, it's considered a best practice to avoid using methods on console. Such messages are considered to be for debugging purposes and therefore not suitable to ship to the client. In general, calls using console should be stripped before being pushed to production.

                    console.log("Made it here.");
console.error("That shouldn't have happened.");

                    Rule Details

                    This rule disallows calls to methods of the console object.

                    Examples of incorrect code for this rule:

                    /*eslint no-console: "error"*/

console.log("Log a debug level message.");
console.warn("Log a warn level message.");
console.error("Log an error level message.");

                    Examples of correct code for this rule:

                    /*eslint no-console: "error"*/

// custom console
Console.log("Hello world!");

                    Options

                    This rule has an object option for exceptions:

                    • "allow" has an array of strings which are allowed methods of the console object

                    Examples of additional correct code for this rule with a sample { "allow": ["warn", "error"] } option:

                    /*eslint no-console: ["error", { allow: ["warn", "error"] }] */

console.warn("Log a warn level message.");
console.error("Log an error level message.");

                    When Not To Use It

                    If you're using Node.js, however, console is used to output information to the user and so is not strictly used for debugging purposes. If you are developing for Node.js then you most likely do not want this rule enabled.

                    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 78.

                    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.

                    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 73.

                    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.
