The instructor is very thorough and concise with the tutorial. I was able to get a better understanding of the Javascript validations and made my own tweaks to my form. AWESOME!

For such a narrow topic, I was hoping for a bit more. I have doubts about the quality of the code. One large function is shown, with nested if else statements. What if I have 20 conditions and there are many more fields? Writing in this way would be difficult and hard to read. For this, JS and CSS layers are mixed, e.g. "el.style.borderColor =" red ", which I don't like either. If I'm wrong, I will read what the author thinks about it. Maybe I don't understand something and I could change higher course rating.

This course is not a complete how to validate a form for various input types, it is a basic form validation course but it walks you through the process fo validation. as I said, still limited to validate certain input types. In the last section, there should have been a "form has been submitted" text after the form has been submitted. After all, you can learn a thing or two if you are new to JavaScript and DOM manipulation. It is kinda outdated but for learning javascript, it is ok.
