当我编写代码时,让我(或其他人)清楚地了解正在发生的事情对我来说非常重要,这样我(或其他人)就不需要在以后浪费时间试图重新弄清楚所有事情。因此,我首先寻求有关回调命名约定的最佳实践。

此外,最近从 PHP (Symfony2) 切换并在我的 IDE 中使用 DocBlock 进行提示,我试图找出一种类似的方法来在我的 Javascript 代码中获得有用的提示。

例如:

# app.js
# .. requires etc

// Question 1. Naming the function (`function importFinishedHandler (..`) makes it easier to debug (see callbackhell.com). But do I really need to assign this to a variable, as it seems to work without, is there any difference?
var importFinishedHandler = function importFinishedHandler (err, data) {
    # handle err or data
};

var importer = new Importer();
importer.import('../path/to/myfile.json', importFinishedHandler);



# importer.js

// Question 2. Is it good practice to name the `callback` here something descriptive such as `importFinishedHandler` (instead of just `callback` which is what I see a lot of people doing), as passed in from the `app.js` file.
// Question 3. When I want to see what parameters the `importFinishedHandler` callback function requires, I need to go back into `app.js` and check manually. In this instance it is pretty easy to see, but when files get big it isn't. Is there any way to use `Docblock` or something so that my IDE (WebStorm) can give me the correct required parameters?
Importer.prototype.import = function (file, importFinishedHandler) {
    # do import stuff
    importFinishedHandler(null, data);
};

如果有人可以回答这些问题或将我链接到一些带有建议的好文档,那么我将非常感激。到目前为止,我发现这个很有帮助:

但是,诸如此类的搜索查询docblock callbacks并没有提供任何有用的信息。

这可能有助于 JavaScript https://devdocs.magento.com/guides/v2.4/coding-standards/docblock-standard-javascript.html中的 docblock

说到回调命名约定的最佳实践,我认为使用“on”前缀是一个很好的方法onSuccess,例如onFailure. 看看这个reddit评论
