How can I make a place saving function?

I am looking for help making or finding a plugin/script that will have the player re spawn at his last location. Say a player starts at spawn, then moves to another region, then leaves the game for a break. I need help on how that player will re spawn after rejoining at the region that he left at. (kind of like the apocalypse rising thing where it saves your location.)

You will have to save the last position of the player upon leaving on data store
