nodejs javascript find with condition

Hello I have a queue of players and wanted to get the first player that met one of my two conditions, but I am unsure how to do that.

First I get the value of a player (mmr) and wanted to get one (only one) player from the queue that had 5% more or less of this value

My condition I think is this to get 5% more or less:

  const condition = (5/100)*playerOne.mmr + playerOne.mmr
  const condition2 = (5/100)*playerOne.mmr - playerOne.mmr

my function:

makeMatch(playerOne) {
  // make matched players
  const condition = (5/100)*playerOne.mmr + playerOne.mmr
  const condition2 = (5/100)*playerOne.mmr - playerOne.mmr
  const player = playerOne;
  const matchedPlayer = this.players.find();
  // remove matched players from this.players
  this.removePlayers(matchedPlayers);
  // return new Match with matched players
  return new Match(matchedPlayers);
}

I have questions as I would get 5% more or less within my find

Check out the documentation for the find function it details this use case. Here's the line that you would want for the desired result.

const matchedPlayer = this.players.find((playerTwo) => playerTwo.mmr > condition || playerTwo.mmr > condition2);

You can try something like this:

if (player.condition1 > condition1*0.95 && player.condition1 < condition1*1.05) {
   // then you keep the player
} else {
   // else you remove it from the list
}

Also, I would highly reccomend you to give better identifiers to the variables. Instead of condition1, something like age, height, weight.
