在承诺语法之前无效 [英] void before promise syntax

问题描述

将 void 放在 promise 之前的实际影响是什么?

What is the actual impact of putting void before promise?

async function doAsyncStuff(){
...
}

function nonAsyncFunction(){
  void doAsyncStuff();
}

我找不到任何官方文档，但它必须在解决no-floating-promises TSLint 错误.

I couldn't find any official documentation for this, but it must be doing something as it resolves no-floating-promises TSLint error.

推荐答案

void 是一个运算符，它接受右侧的值并计算为 undefined.

它解决了无浮动承诺，因为它对承诺做了一些事情(或者更确切地说，明确地什么都不做).

It resolves no-floating-promises because it does something (or rather, explicitly nothing) with the promise.
