英文:
Do variables in a loop get garbage collected or do they stay in memory?
问题
这段代码中的变量在循环结束后会被垃圾回收，所以不会永远在内存中存在。如果你想更高效地处理，只需要在将int转换为string并追加到byte之后，及时释放sSteamId变量的内存。
以下是修改后的代码示例：
for _, id := range steamIds {
sSteamId := strconv.Itoa(id)
requestURI = append(requestURI, ","+sSteamId...)
// 在这里添加代码，手动释放 sSteamId 变量的内存
sSteamId = ""
}
通过将sSteamId变量设置为空字符串，可以让垃圾回收器更早地回收该变量所占用的内存空间。这样可以更有效地管理内存。
英文:
Does the variable in this bit of code get garbage collected after the loop finishes or do I have X amount of sSteamId variables floating in memory forever?
If it does, how can I do this more efficiently? I only need sSteamId long enough to convert an int to a string and then append it to a byte, then it's no longer needed
for _, id := range steamIds {
sSteamId := strconv.Itoa(id)
requestURI = append(requestURI, ","+sSteamId...)
}

他们将被垃圾回收，因为每次迭代时对它们的引用都会丢失。
英文:
They'll get GC'd as any references to them are lost with each iteration.
