About this course

Writing clean, readable code is one of the most important skills for any developer, yet naming functions based on what they actually do remains a constant challenge. In functional programming, function names should clearly convey the relationship between their inputs and outputs. This text-only course guides you through the core principles of functional-light JavaScript, focusing on naming semantics. You will learn how to transition from generic helper names to precise, semantic terms that make your codebase self-documenting and easy to maintain. What you'll learn: 1. Understand the core principles of functional-light JavaScript and declarative programming. 2. Learn how to name functions based on the relationship between their inputs and outputs. 3. Apply semantic naming patterns for common functional utilities like mappers, filters, and reducers. 4. Structure your modern JavaScript code using clean ES6+ syntax, including arrow functions and destructuring. 5. Practice refactoring legacy, imperatively named functions into clear, functional alternatives. 6. Configure basic linting rules to enforce consistent naming conventions across your team. You will start with the fundamental definitions of functional programming terms before diving into practical naming strategies. Through clear written explanations and step-by-step code analysis, you will explore real-world refactoring scenarios that demonstrate semantic naming in action. This course is designed for beginner to intermediate JavaScript developers who want to write cleaner, more readable code. No prior experience with functional programming is required. Start reading today to write highly readable, predictable, and professional JavaScript code.
