Join Two Arrays in ColdFusion

Question

Is there a built-in way to join two arrays in ColdFusion, similar to JavaScript\'s array.concat()?

Answer 1

You can easily concatenate two lists like this:

So, first convert your two arrays to lists using ArrayToList(). Combine the two lists with the ListAppend() and then convert the answer back to an array with ListToArray().

I don't know how efficient this is, but the code is very simple. I'd love to use the arrayAppend() but I'm in ColdFusion 8.
