I am currently running the DnD 5e module Curse of Strahd, and time/travel is seeming important in this campaign. I am looking to build a 2D array variable with the numbers being tied to the locations, and then having the times be stored in the array spot. Example: [0] => [5] = 2.7 hours. My questions are: How do I create a 2D array in javascript (I know how to do it in other languages). How would you recommend I fill in the times? Thanks in advance!
