1. 在使用了 setTimeout 之后，并且回调函数被执行完毕，是否有必要使用 clearTimeout 清除这个定时器？如果不清除，是否会造成内存泄露？

What did AI Help answer?

在使用了 setTimeout 后，当回调函数被执行完毕，通常情况下是不必要使用 clearTimeout 清除这个定时器的。因为一旦定时器的回调函数执行完毕，定时器会自动被清除，不会造成内存泄露。只有在需要提前取消定时器的情况下，才需要使用 clearTimeout 来清除定时器。

你可以在 MDN 文档中了解更多关于 setTimeout 和 clearTimeout 的信息。

1. After setTimeout is used and the callback function is executed, is it necessary to clear the timer with clearTimeout? If not, will it cause a memory leak?

What did AI Help answer?

After using setTimeout, when the callback function has finished executing, it is usually not necessary to clear the timer with clearTimeout. This is because once the timer's callback function finishes executing, the timer will be cleared automatically and will not cause a memory leak. You should only use clearTimeout to clear the timer if you want to cancel it early.

You can learn more about setTimeout and clearTimeout in the MDN documentation. (https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/clearTimeout).
