WordPress Autosave is one of webmaster features that gives them peace of mind while editing a post or page on many of our websites.
If you’ve worked with some other CMS where there is no autosave, you might have experienced that horrible moment, when as soon as you press “Save”, your login times out and you lose everything.
This feature is extremely important and useful because it prevents the risk of losing data. For example, if you were working on a post and your browser crashed all the sudden, then your work will not be lost (thanks to autosave).
WordPress autosave prevents that tragic story, which has happened time and time again to so many webmasters.
