Compare single array schemes

[vaynevayne]

const list  = []
const index=0

When I showed the data structure, the specific implementation was self-evident
This kind of solution achieves undo and redo, is it okay?
This plan seems simple, is there any disadvantage?

Hey @vaynevayne! I'm not sure I fully understand the issue you've raised here. Are you wondering if implementing undo/redo functionality on your own using that structure is practical?

Let me know, thank you!
