Hello!

While the course is discussing client-side validation, one of the use cases is “This can also help us protect our server from malicious code or data from a malicious user.”

Unfortunately, this is incorrect, and might give people the wrong idea (i.e. that client-side validation has use as a security measure).
All of the other examples are correct though, but I heavily recommend that this one gets reworded or deleted, as relying on client-side validation for any security will lead to issues.

Form Validation seems to have jumped right into ‘Requiring an input’ and covered a few topics, but there seem to be other stuff not explained like: action, method, value, etc.

When doing the quiz at the end of the lesson, there are question I don’t seem to have covered? Also, when checking the Cheatsheet there are alot of things listed not covered. Is it expected to Google and do a self study for this particular ‘Form Validation’?
