Function Types

In advanced programming, functions can be categorized into several types:

  • Pure Functions: Always return the same output for the same input, with no side effects. 🌟
  • Higher-Order Functions: Accept functions as arguments or return them as results. 🔁
  • Closures: Combine functions and lexical scope to capture variables. 🧠

📌 For more details on basic functions, see /Documentation/en/FunctionBasics

Higher-Order Functions in Practice

Examples include:

  • Mapping data with map() 📈
  • Filtering elements using filter() 🔢
  • Reducing values via reduce() 📦

Closures & Scope

Closures allow functions to:

  • Access variables from outer scopes even after they're closed. 📜
  • Maintain state between function calls. 🔄
  • Be used for data privacy and encapsulation. 🔒
