no-extra-arguments

November 22, 2023 ยท View on GitHub

You can easily call a JavaScript function with more arguments than the function needs, but the extra arguments will be just ignored by function execution.

Noncompliant Code Example

function say(a, b) {
  print(a + ' ' + b);
}

say('hello', 'world', '!'); // Noncompliant; last argument is not used

Exceptions

No issue is reported when arguments is used in the body of the function being called.

function doSomething(a, b) {
  compute(arguments);
}

doSomething(1, 2, 3); // Compliant
