    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"

    Use == if you meant to do a comparison or wrap the expression in parentheses to indicate you meant to assign in a condition.

                  if change = attribute_change(attr_name)

    This cop checks for assignments in the conditions of if/while/until.

    Example:

    # bad
    
    if some_var = true
      do_something
    end

    Example:

    # good
    
    if some_var == true
      do_something
    end
