[BUG] ele.setAttribute vs ele.attribute

[krausyd]

There is an error in the section When to use setAttribute instead of dot notation?, you mention the case of data- attributes:

Because they're not standard HTML attributes, you can't set them using dot notation. You have to use setAttribute.

This is not right. You can always use the dataset attribute, which is a named set, and use the array notation to set the value you want to set. Example:

ele.dataset['count'] = 10;
