JS Parâmetro vs Argumento

function example(parameter) {
  console.log(parameter); // Output = foo
}

const argument = 'foo';

example(argument);

// Function parameters are the names listed in the function's definition.
// Function arguments are the real values passed to the function.
// Parameters are initialized to the values of the arguments supplied.
