Destructuring vs manual access

a.js

function foo(...args) {
  const [state, action] = args;
}

function bar(...args) {
  const state = args[0];
  const action = args[1];
}

result.js

"use strict";

function foo() {
  for (var _len = arguments.length, args = Array(_len), _key = 0; _key < _len; _key++) {
    args[_key] = arguments[_key];
  }

  var state = args[0];
  var action = args[1];
}

function bar() {
  var state = arguments[0];
  var action = arguments[1];
}
