/* 
// No return is needed, such function is:
function add(number1, number2) {
    console.log(number1, number2);
    var sum = number1 + number2;
    console.log(sum);
}

add(45, 15); 

// Output ||
// 45, 15
// 60

/* 
// A return is needed from the function for future use, such function is:
function add(number1, number2) {
    console.log(number1, number2);
    var sum = number1 + number2;
    return sum;
}

var total = add(80, 20);
console.log(total);

// Output ||
// 80, 20
// 100

// Another example of Function Return in JS
// How much Singaras can be bought in how much money

    return quantity;
}

var myTaka = 150;
var singaras = bringSingara(myTaka);

// Eating Singaras: 15

// Simple Case :: Re-using the returned data from a function

/* 
// Complex Case :: Re-using the returned data from a function 
// Addition of numbers
function add(num1, num2) {
