## What it is
An educational guide explaining why imperative loops (for, while, forEach) can be replaced with recursion and higher-order functions in JavaScript. It covers correctness, maintainability, and functional programming concepts like folds and f-algebras.

## Use cases
- learn to replace for loops with recursion in javascript
- understand why loops cause off-by-one and infinite loop bugs
- study functional programming alternatives to imperative iteration
- teach junior developers about higher-order functions like map and reduce
- explore tail recursion and f-algebras in javascript
- refactor loop-heavy code toward declarative style

## When to choose
- you want a conceptual guide to loop-free, functional-style JavaScript
- you are teaching or learning functional programming fundamentals
- you need arguments and examples for avoiding off-by-one errors and hidden state

## When to avoid
- you need a production library or utility for iteration
- you require maximum runtime performance for hot loops
- you work in a language or codebase where imperative loops are idiomatic

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: programming-languages, tutorials, developer-tools
- platform: cross-platform
- tags: functional-programming, recursion, higher-order-functions, javascript, tail-recursion, fold, awesome-lists, algorithms, nodejs
