change to
commandArcher(archer, i, archer.length);
I don’t think that does anything, its just the blue text that tells you what to do, but sure you guys are the teachers here 
teachers? no just coder(me)
Whatever, still fail, my soldiers attack the ogres and then die:
/// Hushbaum has been ambushed by ogres!
// She is busy healing her soldiers, you should command them to fight!
// The ogres will send more troops if they think they can get to Hushbaum or your archers, so keep them inside the circle!
// Soldiers spread out in a circle and defend.
function commandSoldier(soldier, soldierIndex, numSoldiers) {
var angle = Math.PI * 2 * soldierIndex / numSoldiers;
var defendPos = {
x: 41,
y: 40
};
defendPos.x += 10 * Math.cos(angle);
defendPos.y += 10 * Math.sin(angle);
hero.command(soldier, "defend", defendPos);
}
// Find the strongest target (most health)
// This function returns something! When you call the function, you will get some value back.
function findStrongestTarget() {
var mostHealth = 0;
var bestTarget = null;
var enemies = hero.findEnemies();
// Figure out which enemy has the most health, and set bestTarget to be that enemy.
for(var i=0; i < enemies.length; i++) {
if (enemies[i].health > mostHealth) {
mostHealth = enemies[i].health;
bestTarget = enemies[i];
}
}
// Only focus archers fire if there is a big ogre.
if (bestTarget && bestTarget.health > 15) {
return bestTarget;
} else {
return null;
}
}
// If the strongestTarget has more than 15 health, attack that target. Otherwise, attack the nearest target.
function commandArcher(archer) {
var friends = hero.findFriends();
for(var i=0; i < friends.length; i++) {
if(friend.type == "archer"){
var archerfindNearestEnemy = friend.distanceTo(enemy) < 15;
}
var nearest = archerfindNearestEnemy;
if(archerTarget) {
hero.command(archer, "attack", archerTarget);
}
else if(nearest) {
hero.command(archer, "attack", nearest);
}
}
}
var archerTarget = null;
while(true) {
// If archerTarget is defeated or doesnt exist, find a new one.
if(!archerTarget || archerTarget.health <= 0) {
// Set archerTarget to be the target that is returned by findStrongestTarget()
archerTarget = findStrongestTarget();
}
var friends = hero.findFriends();
var soldiers = hero.findByType("soldier");
// Create a variable containing your archers.
var archers = hero.findByType("archers");
for(var i=0; i < soldiers.length; i++) {
var soldier = soldiers[i];
commandSoldier(soldier, i, soldiers.length);
}
// use commandArcher() to command your archers
for (var q=0; q < archers.length; q++){
var archer = archers[q];
commandArcher(archer, i, archer.length);
}
}
My mistake - change the q to i
add my solution to the function.It makes the soldiers heal
Change to
var nearest = archer.findNearestEnemy

here:
function commandSoldier(soldier, soldierIndex, numSoldiers) {
var angle = Math.PI * 2 * soldierIndex / numSoldiers;
var defendPos = {
x: 41,
y: 40
};
defendPos.x += 10 * Math.cos(angle);
defendPos.y += 10 * Math.sin(angle);
if(soldier.health > 60) {
hero.command(soldier, "defend", defendPos);
}else {
hero.command(soldier, "defend", {'x': 40, 'y': 42})
}
}
