// === REQUIREMENTS === //
// 1) 2 players; Players take turns
// 2) when player click submit, game rolls 2 dice and show dice rolls;
// say 1 and 5
// 3) Player pick the order of dice they want, e.g 51, they can specify second dice go first
// after both players rolled and chosen dice order, player with higher combined number wins

// === PROBLEM BREAKDOWN AND PLANNING === //
// ver 1. roll 2 dice; returns output for 1 player. Player choose dice order and get correct return output
// ver 2. Refactor code to include player 2
//-need Global variables for current player; allPleyerScore
// ver 3. Implement compaing dice scores and declare winner
// ver 4. Reset game such that players play continually without refreshing page
// Declarring Global Variables
