How WebDriver Actions works

I am interested in mechanism of WebDriver actions. For example

 var actions = new Actions(driver);
 var action = actions.MoveToElement(element).Build();
 action.Perform();

How method MoveToElement() works? Is it a wrapper on javascript? If yes, is it possible to get this javascript code?

moveToElement is implemented based on coordinates. following is the code for moveToElement is the following 

public Actions moveToElement(WebElement toElement) {
    this.action.addAction(new MoveMouseAction(this.mouse,
            (Locatable) toElement));
    return this;
}


public abstract interface Locatable {
public abstract Coordinates getCoordinates();
}

public class MoveMouseAction extends MouseAction implements Action {
public MoveMouseAction(Mouse mouse, Locatable locationProvider) {
    super(mouse, locationProvider);
    if (locationProvider == null)
        throw new IllegalArgumentException(
                "Must provide a location for a move action.");
}

public void perform() {
    this.mouse.mouseMove(getActionLocation());
}
}

No javascript. It uses coordinates to move mouse there. Check this link.

So - I was actually curious about the mechanics myself, so I took a look through the selenium source, and my determination is that - no. It does not use javascript. It uses Java's ability to read / move the mouse positions / keyboard drivers / etc, and then when you call perform(), it has a queue of Actions that it will then perform.
