Fetch values in an array with a condition

Question

Well I have a Queue ( that is a collection of players)

class Queue {
  constructor() {
    this.players = [];
  }

  // addPlayers add multiple players into queue
  addPlayers(players) {

      this.players = this.players.concat(players);
  }

  // addPlayer adds a single player into queue
  addPlayer(player) {
    if(!this.players.find(p => p.id == player.id)){
      this.players.push(player);
    }
  }

  // removePlayers remove multiple players from queue
  removePlayers(players) {
    players.forEach(p => {
      this.removePlayer(p);
    });
  }

  // removePlayer removes a single player from queue
  removePlayer(player) {
    this.players = this.players.filter(p => p.id !== player.id)
  }

  // getPlayers return players that are currently on queue
  getPlayers() {
    return this.players;
  }

  searching(id) {
    const firstPLayer = this.players.find(p => p.id == id)
    const { mmr } = firstPLayer
    const secondPlayer = this.players.find((playerTwo) => playerTwo.mmr < (5 / 100) * mmr + mmr && playerTwo.mmr > mmr - ((5 / 100) * mmr) && playerTwo.id != firstPLayer.id);
    if(!secondPlayer){
      return null;
    }
    const matchedPlayers = [
      firstPLayer,
      secondPlayer
    ]
    // remove matched players from this.players
    this.removePlayers(matchedPlayers);
    // return new Match with matched players
    return matchedPlayers;
  }
}

and then I need to remove from this list two players ( players ) randomly who obey a condition that has mmr equal or between 5% for more or for less.

Or it takes 2 players who meet this condition

I thought to do this using a filter and dps a Slice(0.2) but in my filter I can’t imagine how I could filter the players that have mmr equal or between 5% more or less I don’t think that’s possible. Could someone help me with this?

Good afternoon, I don’t know if I understood you right but how do you need to validate if mmr is greater/less than 5%, you can validate if mmr < 11 will meet the 2 conditions.
