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"

      Cognitive Complexity is a measure of how hard the control flow of a function is to understand. Functions with high Cognitive Complexity will be difficult to maintain.

      Define a constant instead of duplicating this literal "Cache miss - processing\n" 3 times.
      Open

      Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.

      On the other hand, constants can be referenced from many places, but only need to be updated in a single place.

      Noncompliant Code Example

      With the default threshold of 3:

      function run() {
  prepare('action1');                              // Non-Compliant - 'action1' is duplicated 3 times
  execute('action1');
  release('action1');
}

      Compliant Solution

      ACTION_1 = 'action1';

function run() {
  prepare(ACTION_1);
  execute(ACTION_1);
  release(ACTION_1);
}

      Exceptions

      To prevent generating some false-positives, literals having less than 5 characters are excluded.

      Remove this commented out code.

      Programmers should not comment out code as it bloats programs and reduces readability.

      Unused code should be deleted and can be retrieved from source control history if required.
