I've made some custom methods for working with arrays. They're mostly pretty simple, but handy to have in the toolbox. It's nice to share, so here they are! (Code below.)

ArraySplice(InputArray, SpliceIndex, DeleteLength, InsertArray)
Removes and inserts elements in an array and returns a copy of it.		InputArray		Array		The array to be modified
		SpliceIndex		Int		The index of the first element to be deleted and the point to insert new elements
		DeleteLength		Int		The number of elements to be deleted, including the element at SpliceIndex
		InsertArray		Array		The array to be inserted (optional)
ArraySlice(InputArray, SliceIndex, SliceLength)
Returns a portion of an array.		InputArray		Array		The array to be extracted from
		SpliceIndex		Int		The index of the first element to be returned
		DeleteLength		Int		The number of elements to be returned, including the element at SliceIndex
ArrayConcat(InputArray1, InputArray2)
Returns an array made by joining two arrays together.		InputArray1		Array		The first array to join
		InputArray2		Array		The second array to join
ArrayReverse(InputArray)
Returns an array that is the input array in reverse order.		InputArray		Array		The array to be reversed
ArraySort(InputArray, Descending)
Sorts a numeric array and returns a copy of it.		InputArray		Array		The array to sort. Must contain only numbers or integers
		Descending		Boolean		If true, the sort will be from highest to lowest (optional)
ObjectArraySort(InputArray, Descending, Renumber)
Sorts an array consisting of objects.		InputArray		Array		The array to sort. Must contain only objects, which must all have a property "Index"
This was made for a specific purpose.		Descending		Boolean		If true, the sort will be from highest to lowest (optional)
You may or may not find it useful!		Renumber		Boolean		If true, the objects' "Index" properties will be updated to reflect the new order (optional)

And finally, here's all the code:
