-- From the previous lesson
type Item<T> = {
    id: number,
    name: string,
    data: T,
}

-- NEW: create an item, store it, return it
local function addItem<T>(inventory: {Item<T>}, name: string, data: T): Item<T>
    local item: Item<T> = {
        id = #inventory + 1,
        name = name,
        data = data,
    }
    table.insert(inventory, item)
    return item
end

-- Build the weapons inventory with the new function
local weapons: {Item<{damage: number}>} = {}
local sword = addItem(weapons, "Iron Sword", {damage = 25})
local axe = addItem(weapons, "Fire Axe", {damage = 40})

print(#weapons)
print(sword.id)
print(sword.name)
print(axe.id)
print(weapons[2].data.damage)
