Prompt:

Please, solve the following issue. Title: feat: add code versions and an option to revert to a previous version. Description: Goal: let the user revert to the previous code version
Proposed implementation:

• every time the user submits code, store it separately, don't overwrite the previous code version
  • we can use filenames with dates in them, for example: <userid>-<timestamp>.js
  • use a special name, like <userid>-latest.js for the latest code version so we can quickly retrieve it by path
• add a modal that will allow the user to view previous submissions in the UI and revert to them
  • the button to open a modal should be above the code editor
  • the modal left side should be occupied by the read-only code editor
  • the modal on the right side should be occupied by the list of versions
  • user can click any of the versions to preview them in the modal
  • user can click the restore button to restore the version
  • restoring the code doesn't create a new version until the user submits the code again
    Let me know if you want to work on this ticket and if you have any questions!

Cost: $0.0062 USD.
