Randomly extract one token present on the map: how can I do this?

Hello, I'm a pro user with a bit of experience on real life programming (I'm not experienced in javascript but it's not relevant) .... how can I randomly select a unit in the battlefiled? I need a rollable table with adjustable size since unit are also eliminated and inserted in the battlefield.... I think the best way to do this is using API: how can I obtain a list of the tokens present in a map?

What do you want to do with that random token?

Simply print is name/ID on the chat in oder to use it. You can think about this as an alternative way to determine initiative.

Yeah, API is going to be your best bet there.

The  TokenFate script  does just that - randomly chooses a single token from a group of selected tokens.   

Thank you very much!
