What's the best way to use javascript get data attribute from an element? or How do you properly use

I’ve had bugs with javascript get data attribute too! Turns out I was mixing up hyphen-case and camelCase.

`.dataset` converts `data-my-attr` to `myAttr`, while `getAttribute()` keeps it as-is.

So if your code’s buggy, check your casing!

MDN has a great guide on this—worth a peek.
