TYPES OF FUNCTION

Named Function:

A function that has its own name when declared. It’s easy to reuse and debug because the name shows up in error messages or stack traces.

function greet() {
  return "Hello!";
}
console.log(greet());

Output:Hello

Anonymous Function

An anonymous function is a function defined without an explicit name. It is commonly used as a callback or assigned to a variable.

const greet = function() {
  return "Hi there!";
};
console.log(greet());

Output: Hi there

Function Expression:

A function expression is a function created as part of an expression and assigned to a variable or passed to another function. It can be named or anonymous.

const add = function(a, b) {
  return a + b;
};
console.log(add(2, 3));

Output:5

Arrow Function:

A new way to write functions using the => syntax. They are shorter and do not have their own this binding, which makes them useful in some cases.

const square = n => n * n;
console.log(square(4));

Output:16
