How to display the user's position on the map?

Question

JavaScript

Hello, tell me how to implement a mini navigator on the site, for example, display the user's point on a Google map with a route, and delete the path line as you go along it?
I suspect that without deep knowledge of cartography and a detailed study of api - no way)
Maybe there is at least an option to display the user's location point along with route lines on the map?

And for one more question in the subject, it was always interesting how to perform an action on the site, run a script for example, or go to the url when reaching a point on the map?

Thanks for answers.

I know that it is possible to share a location point, but what you want is most likely only possible if you are a google partner.
