按状态列出任务的函数

-- 管理器中每个任务都遵循的结构
type Task = {
    id: number,
    title: string,
    done: boolean,
}
local tasks: {Task} = {
    {id = 1, title = "Learn Luau types", done = false},
    {id = 2, title = "Build a task manager", done = false},
    {id = 3, title = "Write tests", done = true},
}
-- 用下一个可用的 id 创建任务，并将其添加到列表中
local function addTask(list: {Task}, title: string): Task
    local newTask: Task = {id = #list + 1, title = title, done = false}
    table.insert(list, newTask)
    return newTask
end
-- 将具有此 id 的任务标记为完成，并返回是否找到了该任务
local function completeTask(list: {Task}, id: number): boolean
    for _, t in ipairs(list) do
        if t.id == id then
            t.done = true
            return true
        end
    end
    return false
end
-- 试试看
print(completeTask(tasks, 1))
print(tasks[1].done)
print(completeTask(tasks, 99))
