How do I duplicate an array without effecting the original one?

Probably a stupid question. I’m trying to write a program which will solve a puzzle in the fewest number of steps. But it’s hard for me to make an array that it won’t overwrite! Code in question:

var puzzle = [2,1,3,4,5,6,7,8,9]
var solveseed = [1,2,3,4,5,6,7,8,9]
var workingpuzzle = []
var ntries = 3

func _ready():
	for i in ntries:

func sort_array(oldpuzzle: Array):
	var steps = 0
	workingpuzzle = oldpuzzle
	#ax = newpuzzle.size()
	if workingpuzzle.size() > 9:
		print_to_console("ERROR: Too many terms in array.")
	elif workingpuzzle.size() < 9:
		print_to_console("ERROR: Not enough terms in array.")
	for i in solveseed:
		var x = workingpuzzle.find(i)
		var y = find_correct_place(i)
		if x != -1 && x != y:
			steps += 1
			var swappedterm = workingpuzzle[y]
			print_to_console(String(steps) + ": " + String(i) + " swapped with " + String(swappedterm))

I tried to make a decoy array with “working puzzle” but “puzzle” just gets solved, which is not what I want.

Array has a duplicate() function:
