我是否需要从该功能中释放或释放地图？

I am new to golang, and I made a function which returns a map, but I do not know if it will cause a memory leak. the code like below

func ParseParams(data string) map[string]string {

    params := strings.Split(data, "&")

    m := make(map[string]string)

    for idx := range params {

        vals := strings.Split(params[idx], "=")
        m[vals[0]] = vals[1]
    }

    return m    
}

So, I would like to know if it is necessary to release or free the map ? or do something to avoid the memory leak. Thanks!

Go is garbage-collected so there is no possibility of a memory leak here.
