//This outcome matrix returns a result based on the left players point of view
//so by simply putting the second player first you get the inverse result
//Make sure that this is defined at the initialization of the rock paper scissor game
//You do not want to be redfining this every round, since this does not change

//Result resolution
console.log(Outcome[(ChoiceA[0]+ChoiceB[0]).toLowerCase()] ?? "Input Error")
//take the first letter of both players choices, then combine them and make them lowercase
//then try to access the pair of the combined choices
// for example Rock vs Scissor would boil down into Choice[rs] if you want player 1s result and Choice[sr] if you want player 2s result
