This backups changes to localStorage so that if the user accidentally refreshes the page or navigates away then they don't lose their work. Upon loading the page, if there is a backup in localStorage then the data will be restored and analysed.
If unsaved changes are detected, then a
Resetbutton appears in the upper right corner. Clicking this button will clear the local storage and return the editor to the default state:Thanks!
