Java Script "coding"

I'm working on developing an ai for a game called fox and geese it’s part of my project for the class. The rule of the game is that the fox can jump a duck if the duck was next to the fox and has no other duck to block the fox jump. the task required from me is: To block the fox from jumping another duck; One way to do that is to check first if there is any jumps on the board using the function (populateByJumpDetection) then check if there is any duck that can move to that spot.

If fox can jump goose

Store the position

For each position a fox can jump to

Check If any goose can move to position

Add potential move
