I have two array collections, and they both have a field in common: sourceCode

I would like to push the data from the 2nd into the first. What's the best way to accomplish this?

If you want to merge two array collections, you will use the addAll() method. Example below:
var ac1:ArrayCollection;
var ac2:ArrayCollection;
 
// .. .some code ...
 
// merge ac2 into ac1
ac1.addAll( ac2 );
 
// merge ac2 into ac1 at index 5
ac1.addAllAt( ac2, 5 );
 
// add single object
ac1.addItem( new Object );

Thanks. So would I use a cursor on ac1, and then loop through ac2, and when there is a match on the sourceCode on ac1 == ac2, push ac2 into ac1 on that index...somehow?

Mind showing an example? In my scenario, ac2 will have a lot more sourceCode(s) than ac1. So I only want to push it if there is a match.

Try something like this:
var ac1:ArrayCollection;
var ac2:ArrayCollection;
 
// .. some code ..
 
var currentAc1Object:Object;
var currentAc2Object:Object;
 
for each( currentAc1Object in ac1 ) {
   for each( currentAc1Object in ac2 ) {
      if( currentAc1Object.sourceCode == currentAc2Object.sourceCode ) {
         ac1.addItemAt( currentAc2Object, ac1.getItemIndex(currentAc1Object) + 1 );
      }
   }
}
