accessing variables from executescript function

Question

I'm looking to set some data dynamically during testing using browser.executescript. Something like:

var x;
browser.executeScript(function () {
  var something = x;
});

But x seems to be out of the scope of the function being run. Is there a way for me to pass arguments that will be in the inner scope?

Any help greatly appreciated C

Pass the arguments inside arguments:

Any arguments provided in addition to the script will be included as script arguments and may be referenced using the arguments object. Arguments may be a boolean, number, string, or webdriver.WebElement. Arrays and objects may also be used as script arguments as long as each item adheres to the types previously mentioned.

var x;
browser.executeScript(function (arguments) {
  var something = arguments[0];
}, x);

In addition to @alecxe's answer, if you want more readable code, and you can support es6 this seems like a nice option. More info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment

var my, params, go, here;
browser.executeScript(function ([my, params, go, here]) {
  var something = here;
}, [my, params, go, here]);
