Hello, I'm curious about the purpose of using an AngularJS directive as a comment. I've seen some examples where it can display an alert message, even with arguments, but I'm struggling to see the practical use of a directive as a comment. Could someone provide concrete examples of how this feature can be used effectively, or explain its purpose in a different way?
Thank you
One way to utilize directives is by incorporating them as custom tags, attributes, or comments.
In the case of custom tags, it's worth noting that older versions of Internet Explorer may encounter issues and require additional code for compatibility. The AngularJS site provides thorough documentation on this topic.
As for custom attributes, there are no known browser compatibility issues. However, using custom attributes may prevent a page from being W3C validated as correct HTML4 or XHTML. For those concerned about validation, the ability to utilize directives as comments can be advantageous.
It's worth mentioning that HTML5 permits custom attributes that start with "data-" to be considered valid, making this a non-issue for HTML5 pages.
