Hopscotch is an open-source JavaScript library designed to create interactive guided tours on web pages and applications. Developed by LinkedIn and hosted on GitHub, Hopscotch allows developers to introduce features to users through step-by-step instructions and customizable pop-ups. As of now, the project resides in LinkedIn's Attic, indicating that it is no longer actively maintained. This archival status means users can still access the code and documentation, but should be aware that no further updates or official support will be provided.
