Types of Functions in JavaScript

1. Named Functions
This is the traditional way of defining functions in JavaScript, where a function is declared with a name. Named functions are hoisted, meaning they can be called before they are defined in the code.

2. Anonymous Functions
Anonymous functions, as the name suggests, do not have a name. These functions are often used as function expressions or passed as arguments to other functions (callbacks). Since they have no name, they cannot be referenced after their initial use.

3. Arrow Functions
Introduced in ES6, arrow functions provide a shorter syntax compared to traditional functions. Arrow functions are especially useful for writing concise one-liner functions. However, they differ in terms of `this` binding, as they don't have their own `this` context.

4. IIFE (Immediately Invoked Function Expression)
IIFE functions are executed immediately after they are defined. These functions are often used to create private scopes, avoiding the risk of polluting the global namespace with variables or functions.

5. Higher-Order Functions
Higher-order functions either take one or more functions as arguments or return a function as their result. They are a core feature of functional programming in JavaScript. Examples include array methods like `map()`, `filter()`, and `reduce()`.

6. Constructor Functions
Constructor functions are used to create objects with similar properties and methods. These functions act as blueprints, and when invoked using the `new` keyword, they create new instances of objects with shared characteristics.
