FYI, these DOM manipulation tutorials should probably include some discussion of code injection attacks.

I noticed the example only safely inserts user-supplied values to textContent, but a quick mention that user values should never be inserted as code wouldn't be amiss.

There are, however, separate security courses that should be part of every aspiring developer's curriculum.

Wow, okay, you've both given me a bit to think about here! Malachi Gruenhagen - nice pickup in your review of the video, and Steven Parker, as always you've been an invaluable asset to the community! I'll think about a meaningful comment to add to the Teacher's Notes for this video, and suggest that students look further into the course material that Steven has suggested! :-D

Edit: Done!
