A good rule of thumb is that it takes about 1000 hours to use something (in this case, JavaScript) to become professional on it.
However, since you have already coded earlier, you can immediately start helping your friend. Sometimes all that is required is a second set of eyes to look at something, to see a problem.
This is definitely a challenge for a second computer engineer. I would really like to help him.
I will immediately look at his code, and then spend a week making textbooks and take a second look.
Some notes:
Website forms are more than JavaScript. There are several parts:
- JavaScript form itself
- Sanitizing input (in JavaScript) to prevent users from entering bad data
- Sanitizing input after you received it on the server so that users do not send malicious data.
Finally, note that Stackoverflow focuses more on trying to answer specific technical questions, so if your friend has a very specific case where his code failed, you should post it here.
