I 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 ?

Hi Soumya,

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 :)
