I'm pretty much confuse "Parameter" and "Argument" Any TreeHouse Author help me???

Hi Joseph,

Parameter and Argument are often used as synonyms in real world situations.

When you are getting into nuanced conversations however, the difference between the two is that Parameters are what we use when declaring a function, while arguments are the values that we pass into that function upon its execution.

For example:

function exampleFunc(parameter) {
  //parameter is the parameter we refer to when declaring a function
  console.log(parameter)
}

//when a value is passed to the exampleFunc, its value is considered the 'argument' which is assigned to the parameter parameter
exampleFunc("argument");

Essentially what happens when we call exampleFunc with "argument" as its argument is that "argument" is assigned to the parameter parameter of exampleFunc.

Yea totally, I got them mixed up too as well lol check it, "parameters" are the variables being used in the function declaration.

function sum(    numOne, numTwo    ) {...}

So it can be said that the function Sum, has two parameters, numOne and numTwo.

However, when the function is ACTUALLY being called, what is being tossed into the function are the "arguments."

sum(2, 5);

Here, 2 and 5 are the arguments. Also http://stackoverflow.com/questions/1788923/parameter-vs-argument explains it pretty good too.
