What problem does it solve?

Cognitive Load provides a framework to minimize extraneous mental effort in code and design. It teaches how to reduce working memory load by simplifying conditionals, guarding against deep nesting, and favoring composition over inheritance.

Core Features & Use Cases

13 Principles: Extract complex conditionals, use early returns, prefer composition over inheritance, and keep modules deep rather than frivolously shallow.
Guard Clauses: Flatten nested logic to improve readability.
Self-describing Codes: Prefer descriptive statuses over numeric codes.
Framework-Agnostic: Keep business logic separate from framework glue.
Code Review Guidance: Use cognitive-load checklist to audit code for readability.

Quick Start

Run a cognitive-load audit on a function, refactor to remove nested conditionals, extract named booleans, and replace deep inheritance with composition.

FAQPage Schema

How do I reduce cognitive load in my code?▼

Reduce cognitive load by extracting complex conditionals, using early returns to flatten nested logic, and replacing deep inheritance with composition. These techniques minimize mental effort required to understand code structure and intent.

What are guard clauses and how do they improve readability?▼

Guard clauses are conditional checks that exit a function early when preconditions fail, eliminating deep nesting. They improve readability by letting readers follow the happy path without tracking multiple indentation levels.

When should I prefer composition over inheritance?▼

Prefer composition over inheritance to reduce cognitive load from tracking class hierarchies and method resolution. Composition keeps business logic self-contained and easier to reason about than inheritance chains.

How do I audit code for cognitive load during code review?▼

Use a cognitive-load checklist to evaluate functions for nested conditionals, unclear variable names, and inheritance depth. Refactor identified issues by extracting named booleans, simplifying logic, and flattening module structure.

Why should I use self-describing status codes instead of numeric codes?▼

Self-describing status codes reduce cognitive load by eliminating the need to cross-reference numeric values with documentation. Descriptive names communicate intent directly, making code intent immediately clear to readers.
