Consider the following snippet:

const returnsFunc = () => (arg0, arg1) => {
  console.log('arguments: ' + JSON.stringify(arguments));
  console.log('arg0: ' + arg0 + '  ' + JSON.stringify(arguments[0]));
  console.log('arg1: ' + arg1 + '  ' + JSON.stringify(arguments[1]));
};
returnsFunc()(1, 2);

The output is as follows:

arguments: {"0":{"isTrusted":true}}
(index):48 arg0: 1  {"isTrusted":true}
(index):49 arg1: 2  undefined

So the arguments variable for the function being returned from returnsFunc is being shadowed.

Is there a way to access the shadowed arguments variable?

Arrow functions don't have `arguments`. – Barmar Feb 10 '18 at 09:32

An arrow function expression has a shorter syntax than a function expression and does not have its own this, arguments, super, or new.target. – xianshenglu Feb 10 '18 at 09:35
also the way you use arrow function reduce the readability i think, – xianshenglu Feb 10 '18 at 09:36
