Using arrays as queryKey?

[dhanushkac]

Hi,

Can we use ['id', [1,2,3]] as a proper queryKey? Or should we use ['id', [1,2,3]].flat() to make it equivalent with ['id', 1,2,3]?

it doesn't need to be flat - ['id', [1,2,3]] is fine, but it will not be the same as ['id', [1,3,2]], but this should be obvious because arrays have a fixed order.
