Understanding Function return #coding #javascript

In JavaScript, the return statement works similarly to how it does in other languages. It ends the execution of a function and returns a specified value to the location where the function was called. This returned value can then be used or stored in a variable.

Here's a simple example:

javascript

function addNumbers(a, b) {
const result = a + b; // Calculate the sum of a and b
return result; // Return the result to the caller
}

// Calling the function and storing the returned value
const sum = addNumbers(3, 5);
Here’s the breakdown:

Calling the Function: When addNumbers(3, 5) is called, the function takes 3 and 5 as arguments.
Processing: Inside addNumbers, the variable result is set to 3 + 5, which equals 8.
Returning the Value: The return result line sends 8 back to where addNumbers was called.
If you omit the return statement or simply write return without a value, JavaScript will return undefined by default.
