Functions

Question 1

Create a working function that would be a helpful tool for waiters that logs what a customer wants to order?

Answer 1

function takeOrder(topping, crustType) {
console.log('Order type: ' + crustType + 'pizza topped with ' + topping);
}
takeOrder(pineapple and ham, thick crust);

Question 2

When functions return their value, we can use them together and inside one another. How can you expand onto a function that takes the orders for customers and gets the subtotal, the tax, and the grand total?

Answer 2

Var orderCount = 0;
Function takeOrder(topping, crustType) {
	console.log(‘Order: ’ + crustType + ‘ pizza topped with’ + topping);
	orderCount = orderCount + 1;
}

function getSubTotal (itemCount) {
	return orderCount * 7.50;
}


Function getTax () {
	return getSubTotal(orderCount) * 0.06;


}


Function getTotal () {
	return getSubTotal(orderCount + getTax());
}
takeOrder(‘pineapple and ham’, ’thick crust’);
console.log(‘Your subtotal is:’, getSubTotal(orderCount))
console.log(‘Your total is:’ getTotal)



Question 3

Answer 3

A global variable can be accessed anywhere and a function variable can only be accessed within it’s function
