Help with random items

[Tazer57]

I'm trying to make a code so that it gives you a random of a certain set of items, but different items are rarer than others. ex dirt has a 50% chaance to get stone 25% chance coal a 20% chance and diamodns a 5% chance.

  const rand = Math.random() * 100;

  if (rand < 50) {
    // 50% de chance -> stone
    api.giveItem(playerId, "stone", 1);
  } else if (rand < 75) {
    // 25% de chance -> coal
    api.giveItem(playerId, "coal", 1);
  } else if (rand < 95) {
    // 20% de chance -> iron
    api.giveItem(playerId, "iron", 1);
  } else {
    // 5% de chance -> diamond
    api.giveItem(playerId, "diamond", 1);
  }
