Applying the DRY principle in Google Apps Script

Question

Trying to do some clean programming in Google Apps Script. Does anyone know how to reuse oft-repeated method/property chains? Example:

var lblDate = app.createLabel("Date")
    .setId('lblDate')
    .setStyleAttribute("fontFamily", "\"Helvetica Neue\", \"HelveticaNeue\", Helvetica,   Arial, \"Lucida Grande\", sans-serif")
    .setStyleAttribute("fontSize", "14px")
    .setStyleAttribute("fontSize", "1.4rem")
    .setStyleAttribute("lineHeight", "1")
    .setStyleAttribute("color", "#222222")
    .setStyleAttribute("position", "relative");

This question has many implications for me, but the task at hand (above) is applying Zurb Foundation styles across various form elements using only GAS Javascript.

Any takers?

Could you do something like:

function applyCSS(element, style) {
  for (var key in style) {
    element.setStyleAttribute(key, style[key]);
  }
}

var _zurb1 = 
  {
    "fontFamily": "\"Helvetica Neue\", \"HelveticaNeue\", Helvetica,   Arial, \"Lucida Grande\", sans-serif",
    "fontSize": "14px",
    "fontSize": "1.4rem",
    "lineHeight": "1",
    "color": "#222222",
    "position": "relative"
  }

And then in your main code:

var lblDate = app.createLabel("Date").setId('lblDate');
applyCSS(lblDate, _zurb1);

With the new setStyleAttributes() method I think you can now do away with the applyCSS() function and just use:

var lblDate = app.createLabel("Date").setId('lblDate').setStyleAttributes(_zurb1);
