What is the difference between argument and parameter in javascript or any other language?

Question

Some example would help better in understanding.

Answer 1

“Parameter is the variable in the declaration of a function. Argument is the actual value of that variable that gets passed to that function when it is called/invoked.”

function myFunc (parameter) {
return parameter + 4;
}

myFunc (argument);

I hope you understand it now ;)

Answer 2

thanks Dev .

Answer 3

Simple:

PARAMETER → PLACEHOLDER (This means a placeholder belongs to the function naming and be used in the function body)
ARGUMENT → ACTUAL VALUE (This means an actual value which is passed by the function calling)

This is also good to remember.
