var orderCount=0;
function takeOrder(topping,crustType) {
console.log('Order: ' + crustType + 'crust topped with ' + topping);
return(orderCount * takeOrder);
orderCount = orderCount + 1;
}

function getSubTotol(iteamCount){
return(iteamCount * 7.5);
}

takeOrder("bacon","thin");
takeOrder("sausage","thick");
takeOrder("pineapple","crisp");
console.log(getSubTotal * orderCount)

GUYS NEED HELP HERE I'VE BEEN TRYING THIS FOR HOURS BUT I DONT KNOW WHAT TO DO NOW HELLLLLP!!!

+++ function talk

Please read the Function talk
and concentrate on
- parameter
- argument
- calling a function
- usage of the return statement

the FUNCTION talk

var myFunc = function( param1, param2) {
       //Begin of  anonymous FUNCTION-BODY
       //VARIABLE -myFunc- has an -anonymous function- assigned
       //this -anonymous function- has 2 PARAMETERS param1 and param2
       //param1 and param2 PARAMETERS are used 
       //as -local- VARIABLES throughout the FUNCTION-BODY

      console.log( param1 + " and " + param2 ) ;

      //End of anonymous FUNCTION-BODY
};

If you want to call/execute the anonymous function
you will have to add a pair of parentheses to the variable myFunc
like
myFunc();
As the anonymous function was defined
as having 2 parameters
you have to provide 2 arguments
in our case 2 string VALUES "Alena" and "Lauren"
like
myFunc("Alena","Lauren");

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

function with 1 parameter using return-statement

var myFunction = function( param1 ) {
       //Begin of FUNCTION-BODY
       //myFunction =function= has 1 PARAMETER param1
       //this param1 PARAMETER is used as a -local- VARIABLE
       //throughout the FUNCTION-BODY

      return param1;

      //End of FUNCTION-BODY
      };

you have defined a myFunction function
which takes 1 parameter param1
this param1 parameter is used
as a variable throughout the FUNCTION-BODY.

If you want to call/execute this myFunction function
and this myFunction function was defined
as having 1 parameter param1
you will have to provide 1 argument
in our case a "number VALUE" 4
myFunction( 4 );

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

============================================

As you are using the return-statement in your myFunction function
you will only get a return-value no-display.
You can however capture this return-value in a variable
and then use the console.log()-method to do a display.

var theResult = myFunction( 4 );
console.log( theResult );

OR directly

console.log( myFunction( 4 ) );

#3

You will have to use orderCount as an argument in your getSubTotal function


#4

var orderCount=0

function takeOrder(topping,crustType){

console.log('Order:'+ crustType +' crust topped with ' + topping);

return(orderCount * takeOrder);

orderCount = orderCount + 1;

}

function getSubTotal(itemCount){

return(itemCount * 7.5);

}

takeOrder("bacon", "thin");

takeOrder("sausage", "thick");

takeOrder("pineapple","crisp");

console.log(getSubTotal(orderCount));

Order:thin crust topped with bacon
Order:thick crust topped with sausage
Order:crisp crust topped with pineapple
0
THANK YOU


#5

If you use a return-statement in a function
the function is directly exited....
Your orderCount = orderCount + 1; would never be reached !!!!

function takeOrder(topping,crustType){
    console.log('Order:'+ crustType +' crust topped with ' + topping);
    ///return orderCount * takeOrder;
    orderCount = orderCount + 1;
    }

========================================
The return statement does NOT use parentheses.
