Functions help you group code into reusable blocks. You need to know the different types to write better code.

Here are the main types of functions:

• Named Functions These use a specific name. function greet() { return "Hello!"; }

• Anonymous Functions These do not have a name. const greet = function() { return "Hi!"; };

• Function Expressions You store a function inside a variable. const add = function(a, b) { return a + b; };

• Arrow Functions A shorter syntax introduced in ES6. const square = n => n * n;

• IIFE (Immediately Invoked Function Expression) This runs as soon as you define it. (function () { console.log("Runs now!"); })();

• Async Functions These handle asynchronous operations. async function fetchData() { return "Data ready!"; }

• Pure Functions These return the same result for the same inputs and have no side effects. function pureAdd(a, b) { return a + b; }

Other important types include:

• Callback Functions
• Constructor Functions
• Generator Functions
• Recursive Functions
• Higher-Order Functions
• Nested Functions
• Rest Parameter Functions

Mastering these will improve your coding skills.
