What is the difference between arguments and parameters in javascript

Answer 1

Argument is often used in the sense of "actual argument" vs. "formal parameter".

The formal parameter is what's given in the function declaration/definition/prototype, the actual argument is what's passed when calling the function, an instance of a formal parameter, if you will.

That being said, they're often used interchangably, or depending on language/community, and I've also heard "actual parameter" &c.

So here, x and y would be formal parameters:

int foo(int x, int y) {
...
}

Whereas here, in the function call, 5 and z are the actual arguments:

foo(5, z);
