What is the best way to assign a return value to a variable in JavaScript?

var robotDeparture = "The robot has set off to buy milk!"
var farewellRobot = return robotDeparture;

I'm attempting to show the content of the robotLeaves variable using a return statement. Furthermore, I intend to assign this return statement to a variable so that I can use it again.

Can anyone recommend websites or resources where I could find information on how to achieve this?

edit: Below is the complete code I am testing:

function getMilk() {
  var shop = 10;
  var robotDeparts = "The robot has left to get milk!";
  var robotReturns = "The robot has returned with 1 bottle of milk!";
  var farewellRobot = return robotDeparture;

  farewellRobot;
  if(farewellRobot) {
    --shop;
    return robotReturns;
    return shop;
  };
}
getMilk();

2nd edit: It appears that I was utilizing the return statement incorrectly! Appreciations to those who provided input!

Not to offend, but the approach you're taking seems a bit unconventional. return doesn't function like a regular function or variable that provides a value; it simply accepts values. When you use it within a function, whatever you return is what will be obtained when calling the function later on. The return statement marks the end of a function's execution - once it is encountered, the function stops running. Therefore, return does not directly display anything, though the returned value can be passed to another function that does.

function getRobotState() {
  return "The robot has left to get milk!";
}

var robotLeaves = getRobotState(); // Call the function, store the returned value in a variable for future use.
// Display the value
console.log(robotLeaves);
// You may reuse robotLeaves multiple times from this point onwards.
postOnTwitter("Where is the robot? " + robotLeaves);
