Why is this called a parameter and not an argument?

Question

in lesson 1 (see below) i took a reference of the video that tought me the difference between a parameter and an argument. in lesson 2 there is also a function used. The word they use to describe inside the () is called a /** argument / function executeCallback ( callback) / argument / , but i thougt it would be named a / parameter **/

and that this part of the code inside the () , executeCallback(sayHello); would be the /** argument **/

thanks for taking the time to read this :) greetings, Max

(lesson 1) Function Parameters and Arguments 4:48 with Guil Hernandez https://teamtreehouse.com/library/function-parameters-and-arguments

JavaScript functions can also accept information called arguments0:55 which you pass to the function.0:59 To have a function accept an argument,1:01 you add what's called a parameter inside the parentheses when creating a function.1:04 Inside your function, you can use the parameter just like any variable.1:17 So now, this function is expecting information.1:22

Each time you call the function, you need to pass it the information,1:25 also called passing an argument to the function.

To summarize, a function parameter represents a value that1:38 you supply to the function via an argument so1:42 that the function could do something with that value.

function goToCoffeeShop ( drink)/** parameter /{ alert(Your ${drink} is on the way!); } goToCoffeeShop (Espresso ); / argument **/ goToCoffeeShop (Coffee );

(lesson 2) Creating a Simple Callback Function3:42 with Andrew Chalkley

const sayHello= function() { console.log('Hello'); }

function executeCallback ( callback) /** argument **/ { callback(); }

executeCallback(sayHello);

here's a single function called sayHello. It logs out Hello to the console.

This will be the callback function we want to execute.

Let's create a function called, executeCallback. With one argument, callback we'll call the callback function by using parentheses. This is in essence what any function requiring a callback would do. It would execute / invoke/call the callback with (because of the) parentheses.

When you use a function, the value(s) you pass to it are called arguments. But when you define a function, the names you give to the temporary variables that will hold the argument values are the parameters. For examples:

function test(bla) {        // "bla" is a parameter
    return "you said " + bla;
}

let thing = "cheese";
let quote = test(thing);    // "thing" is an argument
