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

Wow, didn’t expect so many great tips! The camelCase vs. hyphen thing explains my bugs.

Gonna stick with `getAttribute()` for now—it’s clearer for my team.

Also, the `||` fallback trick is gold. Thanks y’all! 🎉

(Still curious about the performance diff—might test on jsPerf later.)
