Is there a way to find the index of an array within an array?

It is related to this:

Loop not returning result at each iteration

I have a loop that switches values at every iteration, and I need the result of that operation to be pushed into the arr array so when I return it the result should be [ [ 'b', 'a', 'c' ], [ 'b', 'c', 'a' ] ] but instead it’s returning [ [ 'b', 'c', 'a' ], [ 'b', 'c', 'a' ] ] even though when I console log arg within the loop it returns the expected result. What gives? function test(arg) { let arr = [] for (let i = 0; i < 2; i++) { let savedValue = arg[i] arg[i] = arg[i…

Your original code is asking if any of the array elements are stored in the same place as the array you created for the argument of indexOf, and none of those memory addresses will match up.
