EventTarget 与 Event API

EventTarget 和 Event 对象是一些 Node.js 核心 API 暴露的 EventTarget Web API 的特定于 Node.js 的实现。 EventTarget 和 Event 类都不可用于创建最终用户代码。

const target = getEventTargetSomehow();

target.addEventListener('foo', (event) => {
  console.log('foo event happened!');
});

The EventTarget and Event objects are a Node.js-specific implementation of the EventTarget Web API that are exposed by some Node.js core APIs. Neither the EventTarget nor Event classes are available for end user code to create.

const target = getEventTargetSomehow();

target.addEventListener('foo', (event) => {
  console.log('foo event happened!');
});
