Take data of two teams (player name, credit and role such as WK, BAT, AL, BOWL) and store it. Then allow me to select few players among them and to input minimum and maximum players that needs to be present in the output. Develop a script to generate unique possible combinations with Credit not exceeding 100 of the team.

//Team 1
var team1 = [
  { name: "Player 1", credit: 10, role: "WK" },
  { name: "Player 2", credit: 10, role: "BAT" },
  { name: "Player 3", credit: 10, role: "AL" },
  { name: "Player 4", credit: 10, role: "BOWL" },
  { name: "Player 5", credit: 10, role: "BOWL" },
  { name: "Player 6", credit: 10, role: "BOWL" },
  { name: "Player 7", credit: 10, role: "BOWL" },
  { name: "Player 8", credit: 10, role: "BOWL" },
  { name: "Player 9", credit: 10, role: "BOWL" },
  { name: "Player 10", credit: 10, role: "BOWL" }
];
//Team 2
var team2 = [
  { name: "Player 1", credit: 10, role: "WK" },
