Summary  
This chapter explains how to use the `return` statement in functions to pass data back to the caller (for example, to be printed) and how `return` stops further execution of the function.

General domain of usage  
Mathematical computations (e.g., summing values or calculating geometric areas)

We can **return** any kind of value from a function using a `return` statement. 

function sum(a, b) { 
  return a + b;
}

let result = sum(10, 15);
console.log(result); // Output: 25

## General Syntax
The general syntax of a return statement is 
```js
return <value>;
```

Where `<value>` is optional. If no value is provided, the function returns `undefined`:


function exampleFunc() {
  console.log("In the Function");
  return;
}

let result = exampleFunc();
console.log("Return value if nothing is returned:", result); // Output: undefined

## How It Works?
The return statement **stops the execution** of the function, and returns to the point in code the function where it was called. Therefore, any code after `return` is ignored:



function exampleFunc() {
  console.log(1);
  console.log(2);
  return true; // Execution stops here
  console.log(4); // Ignored
  console.log(5); // Ignored
}

console.log("Before Function Call");
console.log(exampleFunc()); // Output: true
console.log("After Function Call");
