Hello, does anyone know what is wrong? I’m stuck, help please …

Code:

// Calculate the total health of all the ogres.

function sumHealth(enemies) {
    // Create a variable and set it to 0 to start the sum.
    var totalHealth = 0;
    // Initialize the loop index to 0
    var enemyIndex = 0;
    // While enemyIndex is less than the length of enemies array
    while(enemyIndex < enemies.length) {
        var enemy = enemies[enemyIndex];
        // Add the current enemy's health to totalHealth
        totalHealth = enemy[enemyIndex].health;
    }
        // Increment enemyIndex by 1.
        enemyIndex += 1;
    return totalHealth;
}

// Use the cannon to defeat the ogres.
var cannon = hero.findNearest(hero.findFriends());
// The cannon can see through the walls.
var enemies = cannon.findEnemies();
// Calculate the sum of the ogres' health.
var ogreSummaryHealth = sumHealth(enemies); 
hero.say("Use " + ogreSummaryHealth + " grams.");

@Matignacio

totalHealth = enemy[enemyIndex].health;

totalHealth should equal enemy[enemyIndex].health plus totalHealth, so instead of an equals sign, you need to add and assign with +=.

In addition, you’re confusing two of your variable names and have left an important statement (incrementing the index) outside the while loop.

    while(enemyIndex < enemies.length) {
        var enemy = enemies[enemyIndex];
        // Add the current enemy's health to totalHealth
        totalHealth = enemy[enemyIndex].health;           // You can't index into an enemy! Should either be `enemies[enemyIndex]` or simply `enemy.health`
    }
        // Increment enemyIndex by 1.
        enemyIndex += 1;                                  // If you don't increment the index inside the loop, `enemyIndex` will remain at `0` and you'll loop forever.
