Can this be re-written to avoid loops altogether and simply use an array method to splice the array at the specific index?

     undo: (steps = 1) => {
        // Fastest way to clone an array on Chromium. Needed to create a new array reference
        const pastStates = get().pastStates.slice();
        const futureStates = get().futureStates.slice();
        if (pastStates.length) {
          // Based on the steps, get values from the pastStates array and push them to the futureStates array
          for (let i = 0; i < steps; i++) {
            const pastState = pastStates.pop();
            if (pastState) {
              futureStates.push(options?.partialize?.(userGet()) || userGet());
              userSet(pastState);
            }
          }
          set({ pastStates, futureStates });
        }
