安全推送阵列，如何？担心与否？ [英] push to array safely, how to? worry or not?

问题描述

我认为这可能是一个天真的问题。我经常发现我有多个等待返回的xhr请求。我跟踪我在javascript数组中发出的请求。也就是说，当发出新请求时，我将它添加到数组中，然后当线程完成时，我将其从数组中删除。

I think this may be a naive question. I often find that I've got multiple xhr requests waiting on returns. I keep track of the requests I've issued in a javascript array. that is, when a new request is made, I add it to the array, then when the thread completes I remove it from the array.

在多线程操作系统中，我会担心线程交叉，但我知道javascript是单线程的。我应该担心阵列是否一致？

In a multi-threaded OS, I'd be worried about threads crossing but I know javascript is single threaded. Should I worry about the array being consistent?

如果已经询问并回答了这个问题，很抱歉。我看了，没有找到数组安全推送的链接。

Sorry if this has been asked and and answered. I looked and did not find a link around array safe push.

推荐答案

不，你不应该担心。 JavaScript是单线程的，就像你说的那样。

No, you should not worry about it. JavaScript is single-threaded, like you said.
