How to set fill, stroke & color to a group

Question

First of all, I must say I'm a complete beginner in Javascript so please have patience with me.
What I'm trying to do is to set a lot of groups to specific fill, stroke & color using a function.
var docRef = app.activeDocument;
var Reg = docRef.swatches["[Registration]"].color;
var mm = 2.834645;
var lineWidth=0.12*mm;
group1.stroked=true;
group1.strokeColor = Reg;
group1.filled = false;
group1.strokeWidth = lineWidth;
This works, but I have to this for every group and there are lots of them.
So I tried to make a function:
function setAttributes(temp)
temp.stroked=true;
temp.strokeColor = Reg;
temp.filled = false;
temp.strokeWidth = lineWidth;
And then call that function for each group:
setAttributes(group1);
setAttributes(group2);
setAttributes(group3);
etc.
Of course, this doesn't work since I have incredible programming skills
Please help.
Thanks!

The script as it is should ONLY change the path items that are in your 'first level' of group items… If you need to change the properties of path items outside of the groups then you could add another loop… Heres one way you add the extra loop:
var docRef = app.activeDocument;
// Set variable to your color
var reg = docRef.swatches.getByName("[Registration]");
// Set a variable to the document path items collection
var pathList = docRef.pathItems;
// Loop through this list of objects
for (var h = 0; h < pathList.length; h++)     {
     // Change the property values
     pathList[h].filled = false;
     pathList[h].stroked = true;
     pathList[h].strokeColor = reg.color;
     pathList[h].strokeWidth = 2;
// Set a variable to the document groups collection
var groupList = docRef.groupItems;
// Loop through this list of objects
for (var i = 0; i < groupList.length; i++)     {
     // Re-use variable for the groups path items collection
     pathList = groupList[i].pathItems;
     // Loop through this list of objects
     for (var j = 0; j < pathList.length; j++)     {
          // Change the property values
          pathList[j].filled = false;
          pathList[j].stroked = true;
          pathList[j].strokeColor = reg.color;
          pathList[j].strokeWidth = 2;
app.redraw();
