// Map: 映射生成新切片
lo.Map(nums, func(x int, _ int) int { return x*x })
// Find: 找到首个满足条件的元素
v, ok := lo.Find(nums, func(x int) bool { return x > 10 })
// Uniq: 去重并保持顺序
uniq := lo.Uniq([]string{"a","a","b"})
// GroupBy: 按键分组
groups := lo.GroupBy(users, func(u User) int { return u.Age })
// Must: 遇 err/false panic，常用于初始化
t := lo.Must(time.Parse(time.RFC3339, ts))
