5,164 PointsI have doubt in Javascript function : Pass an argument module.
In code challenge it asked : Modify the returnValue function to accept one argument named value.
The accepted answer was :
function returnValue(value) { }
I'm confused whether 'value' was an argument or a parameter ?

In your code challenge what you've entered is a parameter. Which is a variable that goes inside the function parentheses that is a kind of holder for the argument that you will, later on, use in your function call.
//function definition
function returnValue(value) {
}
So you've defined your function above, inside which you'll perform an action that uses the value
parameter.
To give value
a an actual value you would call
the function with an argument
. Like below.
//function call
let functionCall = returnValue(5);
where 5 is your function argument and value is your function parameter.
I hope I've helped with your query :)
